What Is a US Ton?
The US ton (officially called the short ton) is a unit of mass in the United States customary measurement system, defined as:
- Exactly 2,000 pounds (avoirdupois pounds)
- Exactly 32,000 ounces
- Exactly 907.18474 kilograms (by definition from 1959 international agreement)
- 20 hundredweight (where 1 hundredweight = 100 pounds in US system)
The US ton is the standard unit for measuring heavy loads in American commerce, transportation regulations, construction materials, and industrial applications.
US Ton vs. Metric: Key Comparison
US Ton (Short Ton):
- 2,000 pounds (exactly)
- 907.185 kilograms (907.18474 kg precisely)
- Used in United States for trucks, cargo, materials
- Based on 2,000-pound commercial standard
Metric Tonne:
- 1,000 kilograms (exactly)
- 2,204.623 pounds (about 2,205 lb)
- Global standard for international trade, shipping, emissions
- Based on metric system (1,000 kg)
Visual comparison:
- A metric tonne is about 92.8 kg heavier than a US ton (about 205 lb more)
- 1 metric tonne = 1.102 US tons (about 10% heavier)
- 1 US ton = 0.907 metric tonnes (about 10% lighter)
Commercial impact: A 20-ton truck in the US (40,000 lb) equals 18.14 metric tonnes. A 20-tonne truck in Europe (20,000 kg) equals 22.05 US tons. This distinction matters for international shipping, vehicle regulations, and trade contracts.
US Ton vs. Long Ton (UK)
US Ton (Short Ton):
- 2,000 pounds (20 hundredweight × 100 lb)
- 907.185 kg
- Standard in United States
Long Ton (Imperial Ton, UK):
- 2,240 pounds (20 hundredweight × 112 lb)
- 1,016.047 kg
- 12% heavier than US ton
- Used historically in UK, now largely replaced by metric tonne
Difference: The long ton is 240 pounds heavier than the US ton. This originated from different definitions of "hundredweight"—the US uses 100 lb, while the UK traditionally used 112 lb.
When it matters: Historical shipping documents, UK coal trade, and older engineering specifications may reference "tons" meaning long tons (2,240 lb), not US short tons (2,000 lb).
The quintal (symbol: q) is a unit of mass equal to 100 kilograms (220.462 pounds) in the metric system. The term derives from Arabic qinṭār (قنطار), itself from Latin centenarius ("containing a hundred"), reflecting its fundamental definition as "a hundred units" of mass.
The Metric Quintal (100 kg)
The modern metric quintal is precisely defined as:
- 100 kilograms (exact)
- 0.1 metric tons (tonnes)
- 100,000 grams
- 220.462 pounds (avoirdupois)
This standardized definition emerged from France's adoption of the metric system (1795-1799), where the quintal was redefined as exactly 100 kg, replacing the pre-revolutionary quintal of 48.95 kg (100 livres).
Historical Quintal Variants
Before metrication, numerous regional quintal definitions existed:
- French quintal (pre-1795): 48.95 kg (100 livres poids de marc)
- Spanish quintal (quintal castellano): 46.01 kg (100 libras)
- Portuguese quintal: 58.75 kg (4 arrobas)
- Egyptian qinṭār: 44.93 kg (100 raṭls)
- British quintal: 112 pounds (50.80 kg, equivalent to 1 hundredweight)
- Venetian cantaro: 47.66 kg
- Dutch centenaar: 49.4-50.2 kg (varied by city)
- Mexican quintal: 46.01 kg (Spanish colonial)
These variations made international trade complex, contributing to the 19th-20th century push toward metric standardization.
The Quintal in Agricultural Trade
The quintal's strength lies in its practical scale for bulk commodity trade:
- 1 quintal = 2 standard grain bags (50 kg each)
- 10 quintals = 1 metric ton (clean decimal conversion)
- Human-manageable scale: 100 kg is within the range two workers can handle
- Intermediate unit: Bridges small-scale sacks and large-scale tonnage
In commodity markets, prices are often quoted per quintal for crops like wheat, rice, coffee, sugar, and cotton.
Note: The Ton (US) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Quintal belongs to the imperial/US customary system.
History of the Ton (US) and Quintal
Etymology: The "Tun" Wine Cask
The word "ton" derives from the medieval "tun," a large wine barrel or cask used for transporting and storing wine. A standard tun held approximately 252 wine gallons and weighed roughly 2,000 pounds when full.
This practical origin meant "ton" became synonymous with "very heavy load"—approximately the weight that could be carried in one tun cask. The measurement evolved from this real-world shipping container into a standardized unit of weight.
English Origins: Competing Ton Standards
In medieval and early modern England, multiple "ton" standards coexisted, creating confusion in commerce:
1. Wine Ton (Tun): ~2,000 pounds, based on wine cask weight 2. Long Ton: 2,240 pounds, based on 20 long hundredweight (20 × 112 lb) 3. Shipping Ton: Volume-based, used for calculating cargo space, not weight
The long ton (2,240 lb) became the official British standard, formalized in the British Imperial system in 1824. It was calculated as 20 hundredweight, where 1 hundredweight (cwt) = 112 pounds (8 stone × 14 lb/stone).
The short ton (2,000 lb) remained in common commercial use, especially in trades dealing with bulk commodities. It represented 20 hundredweight of 100 pounds each, a simpler rounding for everyday commerce.
American Adoption: The Short Ton (2,000 Pounds)
When American colonists inherited English measurement systems, both long ton (2,240 lb) and short ton (2,000 lb) were in use. After independence, the United States faced a choice between standardizing on one or the other.
Reasons the US chose the short ton (2,000 lb):
- Simpler arithmetic: 2,000 is easier to divide and calculate than 2,240
- Commercial preference: The 2,000-pound ton was already common in American trade
- Hundredweight definition: The US standardized on 100-pound hundredweight (rather than 112 lb), making 20 × 100 = 2,000 lb logical
- Decimal thinking: 2,000 fits better with base-10 calculations
In 1832, the US Treasury Department formally adopted the 2,000-pound ton as the standard US ton, distinguishing it as the "short ton" to differentiate from the British "long ton" (2,240 lb).
Metric Definition (1959)
The 1959 International Yard and Pound Agreement refined the US ton's definition in metric terms:
- 1 pound = 0.45359237 kilograms (exactly)
- 1 US ton = 2,000 pounds = 907.18474 kilograms (exactly)
This metric definition ended ambiguity about the ton's exact mass in international contexts and established clear conversion factors for trade between US customary and metric systems.
Modern Usage: Persistent in US, Metric Elsewhere
Today, the US ton remains dominant in American industry despite global metrication:
Why the US ton persists in America:
- Transportation regulations: Federal trucking regulations use tons (Gross Vehicle Weight Rating in tons)
- Construction pricing: Gravel, sand, concrete priced per ton (2,000 lb)
- Cultural inertia: Generations of American industry built around ton-based systems
- Equipment design: Trucks, scales, loading equipment calibrated in tons
Global trend toward metric tonnes:
- International shipping: Maritime cargo measured in metric tonnes (1,000 kg)
- Carbon emissions: Greenhouse gases measured in tonnes CO2 (metric)
- Scientific use: Research and engineering use metric tonnes exclusively
- Trade contracts: International agreements specify metric tonnes to avoid confusion
Result: The US is the only major economy still using short tons as the primary heavy-weight standard, requiring constant conversion for international commerce.
The quintal's 1,300-year journey from Islamic trade networks to modern agricultural markets reflects the evolution of international commerce and measurement standardization.
Arabic Origins (7th-9th Centuries)
The quintal traces to the Arabic qinṭār (قنطار), borrowed from Latin centenarius ("hundred-weight") or Greek kentenarion (κεντηνάριον). During the Islamic Golden Age (750-1258 CE), Arab merchants dominated Mediterranean, Red Sea, and Indian Ocean trade routes, establishing the qinṭār as a standard for trading spices, grain, textiles, and metals.
The qinṭār typically equaled 100 raṭls (رطل), with the raṭl varying by region from 380-550 grams, making historical qinṭārs range from 38-55 kg. Baghdad's Abbasid Caliphate standardized the qinṭār for taxation and trade regulation around 100 raṭls of approximately 400-450 grams each.
Medieval European Adoption (11th-15th Centuries)
Crusader contact, Venetian trade monopolies, and Reconquista Spain brought Islamic measurement units into European commerce. The quintal entered Romance languages:
- Italian: quintale
- Spanish: quintal
- Portuguese: quintal
- French: quintal
- Catalan: quintar
Each region adapted the concept to their local pound (livre, libra, lira), creating dozens of quintal variants. Venice's cantaro (47.66 kg) dominated Mediterranean spice trade, while Iberian quintals (46-59 kg) became colonial standards in the Americas.
Colonial Spread (16th-18th Centuries)
Portuguese and Spanish colonial expansion exported quintal standards to:
- Latin America: Spanish quintal (46 kg) for silver, cacao, sugar
- Brazil: Portuguese quintal (58.75 kg) for sugar, coffee, gold
- Philippines: Spanish quintal for rice, hemp, sugar (until 1906)
- Goa and Macau: Portuguese quintal in Indian and Chinese trade
These colonial quintals persisted long after independence, with Brazil using the Portuguese quintal until adopting the metric version in the mid-20th century.
French Metric Quintal (1795-1799)
The French Revolution's measurement reform created the metric system, redefining the quintal as exactly 100 kilograms on December 10, 1799 (19 Frimaire, Year VIII).
This represented a radical simplification:
- Old French quintal: 48.95 kg (100 livres poids de marc)
- New metric quintal: 100 kg (100,000 grams)
- Decimal elegance: 10 quintals = 1 ton; 1 quintal = 100 kg = 100,000 g
The metric quintal provided a convenient intermediate unit between the kilogram and the tonne (1,000 kg), ideal for agricultural commerce.
International Adoption (19th-20th Centuries)
The Treaty of the Metre (May 20, 1875) established the International Bureau of Weights and Measures (BIPM) and promoted metric standardization. The 100 kg quintal spread through:
European Metrication:
- Italy (1861 unification): Adopted metric quintal for grain markets
- Germany (1872): Zentner (50 kg) preferred over quintal
- Spain (1852, enforced 1880): Spanish quintal → metric quintal
- Portugal (1852, enforced 1866): Portuguese quintal → metric quintal
Colonial and Post-Colonial Adoption:
- India (1947): British hundredweight replaced by metric quintal
- Pakistan (1947): Adopted metric quintal for wheat, rice, cotton
- Bangladesh (1971): Inherited Pakistani metric quintal
- Francophone Africa (1960s): French colonies adopted metric quintal
- Brazil (mid-20th century): Portuguese quintal → metric quintal
Agricultural Commodity Exchanges:
- Chicago Board of Trade (1848-present): US hundredweight (100 lb, 45.36 kg)
- Brazilian coffee markets (early 20th century): Adopted 60 kg bags (0.6 quintals)
- Indian wheat mandis (markets): Quintals standard by 1950s-1960s
Modern Usage (20th-21st Centuries)
Today, the metric quintal remains active in:
- South Asia: India, Pakistan, Bangladesh use quintals for grain prices
- Latin America: Brazil for coffee/sugar, Argentina for grain
- France and Francophone regions: Agricultural statistics, farm sales
- Mediterranean: Parts of Italy, Spain, Portugal in rural markets
- Africa: Former French colonies (Senegal, Ivory Coast, Mali)
Anglo-American markets largely abandoned the quintal for:
- Metric ton (1,000 kg) in international trade
- US hundredweight (100 lb = 45.36 kg) in American markets
- British hundredweight (112 lb = 50.80 kg) until full metrication (1990s)

Additional Unit Information
About Ton (US) (ton)
How many pounds are in a US ton?
There are exactly 2,000 pounds (lb) in 1 US ton (short ton).
Quick conversion:
- 1 ton = 2,000 lb
- 0.5 ton = 1,000 lb
- 2 tons = 4,000 lb
- 10 tons = 20,000 lb
This is the defining relationship: the US ton is defined as exactly 2,000 avoirdupois pounds.
Is the US ton the same as the UK ton?
No. The US ton (short ton) is smaller than the traditional UK ton (long ton):
- US ton (short ton): 2,000 lb = 907.185 kg
- UK long ton: 2,240 lb = 1,016.047 kg
- Difference: The long ton is 240 lb (12%) heavier than the US ton
Modern UK usage: Today, the UK primarily uses metric tonnes (1,000 kg = 2,205 lb), not long tons. Long tons are historical and rarely used in modern commerce.
When it matters: Historical shipping documents, old engineering specifications, and traditional industries (coal mining, maritime) may reference long tons.
What is the difference between a ton and a tonne?
"Ton" (US short ton) and "tonne" (metric tonne) are different units:
US Ton (Short Ton):
- 2,000 pounds (exactly)
- 907.185 kilograms
- Used in United States
- Symbol: ton, st, US ton
Metric Tonne:
- 1,000 kilograms (exactly)
- 2,204.6 pounds
- Used internationally
- Symbol: t, tonne, MT
Key difference: The metric tonne is about 10% heavier (93 kg or 205 lb more) than the US ton.
Spelling note: "Tonne" (with "ne") specifically means metric tonne; "ton" can mean US short ton or UK long ton, requiring clarification.
How do you convert US tons to metric tonnes?
To convert US tons to metric tonnes, multiply by 0.907185 (or approximately 0.9):
Formula:
metric tonnes = US tons × 0.907185
Examples:
- 1 ton = 0.907 tonnes (just under 1 tonne)
- 10 tons = 9.07 tonnes (about 10% lighter)
- 100 tons = 90.7 tonnes
Reverse conversion (tonnes to tons):
US tons = metric tonnes × 1.102311
- 1 tonne ≈ 1.102 tons (about 10% heavier)
- 10 tonnes ≈ 11.02 tons
Practical approximation: For rough estimates, 1 ton ≈ 0.9 tonnes, or 1 tonne ≈ 1.1 tons.
Where is the US ton used?
The US ton (short ton) is primarily used in the United States for:
Industries and applications:
- Transportation: Trucking regulations, vehicle weight ratings (GVWR)
- Construction: Pricing gravel, sand, concrete, steel by the ton
- Waste management: Landfill fees, recycling tonnages
- Shipping: Domestic cargo weights, freight billing
- Agriculture: Crop yields, livestock feed, commodity trading
- Mining: Coal production, ore extraction
- Manufacturing: Steel, cement, paper production
International use: Almost all other countries use metric tonnes (1,000 kg) instead of US tons. The US is the only major economy still using short tons as the primary heavy-weight standard.
Trade caution: International shipping and trade contracts typically specify metric tonnes to avoid confusion between US tons, long tons, and metric tonnes.
What does "half-ton truck" mean?
"Half-ton truck" is a historical classification for light-duty pickup trucks, not a precise measurement of payload capacity.
Traditional meaning: Originally, "half-ton" meant the truck could carry approximately 1,000 lb (0.5 ton) payload.
Modern reality: Today's "half-ton" trucks (Class 2A) typically have payload capacities of 1,500-2,500 lb (0.75-1.25 tons)—often exceeding the historical "half-ton" rating.
Common "half-ton" models:
- Ford F-150
- Chevrolet Silverado 1500
- Ram 1500
- Toyota Tundra
- Nissan Titan
Other truck classifications:
- Half-ton (Class 2A): ~6,000-7,000 lb GVWR, ~1,500-2,000 lb payload
- Three-quarter-ton (Class 2B): ~8,500-10,000 lb GVWR, ~2,500-3,500 lb payload
- One-ton (Class 3): ~10,000-14,000 lb GVWR, ~3,000-4,500 lb payload
Important: Always check the vehicle's GVWR (Gross Vehicle Weight Rating) and payload capacity listed on the door jamb sticker or owner's manual, not the truck's name.
How much does a ton of gravel weigh?
This question seems circular, but it's asking about volume-to-weight relationship:
By definition: 1 ton of gravel = 2,000 pounds (that's what "ton" means)
But the real question is: How much volume (cubic yards)?
Volume equivalence:
- 1 ton of gravel ≈ 0.60-0.75 cubic yards (depending on gravel type and compaction)
- Loose gravel: 1 ton ≈ 0.75 cubic yards
- Compacted gravel: 1 ton ≈ 0.60 cubic yards
Reverse:
- 1 cubic yard of gravel ≈ 1.3-1.7 tons (2,600-3,400 lb depending on type)
Gravel types and density:
- Pea gravel: ~1.3 tons per cubic yard (lighter)
- Crushed stone: ~1.5 tons per cubic yard (typical)
- Dense granite: ~1.7 tons per cubic yard (heavier)
Practical example: If you need to cover a driveway area of 10 cubic yards, you'll need approximately 13-15 tons of gravel (10 yd³ × 1.3-1.5 tons/yd³).
What is the federal truck weight limit in tons?
The federal limit for trucks on interstate highways in the United States is:
80,000 pounds gross vehicle weight = 40 tons
This includes:
- Truck/tractor weight (tare weight)
- Trailer weight (tare weight)
- Cargo weight (payload)
- Fuel, driver, equipment
Axle limits:
- Single axle: 20,000 lb (10 tons) maximum
- Tandem axle: 34,000 lb (17 tons) maximum
- Total gross: 80,000 lb (40 tons) maximum
Bridge formula: The federal bridge formula determines allowable weight based on number of axles and spacing, which may further limit weight on shorter wheelbases.
State variations:
- Some states allow higher weights on specific routes (e.g., Michigan allows up to 164,000 lb / 82 tons with 11 axles)
- Permits: Overweight permits available for specialized hauling (heavy equipment, modular homes)
Violations: Fines for overweight trucks typically $0.10-$0.20 per pound over limit, escalating for serious violations.
How many tons can a dump truck carry?
Dump truck capacity varies by size and type:
Small dump trucks (single-axle):
- Payload: 5-8 tons (10,000-16,000 lb)
- Examples: Small commercial dumps, landscape trucks
- Typical load: 4-6 cubic yards material
Standard dump trucks (tandem-axle):
- Payload: 10-15 tons (20,000-30,000 lb)
- Examples: Construction dump trucks, municipal trucks
- Typical load: 8-12 cubic yards material
Tri-axle dump trucks:
- Payload: 15-18 tons (30,000-36,000 lb)
- Examples: Heavy construction, aggregate hauling
- Typical load: 12-15 cubic yards material
Transfer dump trucks (multi-axle):
- Payload: 20-26 tons (40,000-52,000 lb)
- Examples: Long combination vehicles, specialized hauling
- Typical load: 16-20 cubic yards material
Limitations:
- Federal limit: 80,000 lb (40 tons) gross vehicle weight
- Truck weight: Tare weight typically 15,000-30,000 lb (7.5-15 tons)
- Net payload: Actual cargo capacity = 40 tons minus truck weight
Material matters: Volume capacity depends on material density (sand ~1.5 tons/yd³, mulch ~0.4 tons/yd³).
What does "tonnage" mean in shipping?
In maritime shipping, "tonnage" can mean several different measurements:
1. Gross Tonnage (GT):
- Volume measurement of ship's entire internal space
- Not weight: Measured in "register tons" (100 cubic feet = 1 register ton)
- Usage: Ship classification, port fees, regulations
- Example: "Cargo ship: 50,000 GT"
2. Deadweight Tonnage (DWT):
- Weight measurement of cargo, fuel, crew, provisions ship can carry
- Actual weight capacity (what most people think of as "tonnage")
- Measured in: Metric tonnes (1,000 kg) internationally, sometimes US tons domestically
- Example: "Bulk carrier: 80,000 DWT" (can carry 80,000 tonnes cargo)
3. Displacement Tonnage:
- Total weight of ship (including ship structure + cargo + fuel + everything)
- Equals weight of water displaced by ship (Archimedes' principle)
- Usage: Naval vessels, ship design
- Example: "Aircraft carrier: 100,000 tons displacement"
4. Net Tonnage (NT):
- Volume of cargo spaces only (excludes engine room, crew quarters)
- Usage: Port fees, canal tolls (based on revenue-generating space)
Modern practice: International shipping primarily uses metric tonnes for weight measurements, while US domestic shipping may use US short tons.
About Quintal (q)
How many kilograms are in a metric quintal?
There are exactly 100 kilograms in 1 metric quintal. This is the internationally standardized definition adopted after the French Revolution (1799) and now used in agriculture worldwide.
How does a quintal relate to a metric ton?
1 metric ton (tonne) = 10 quintals. Since 1 tonne = 1,000 kg and 1 quintal = 100 kg, the conversion is a simple decimal shift. This makes quintals ideal for intermediate-scale agricultural measurements.
Is a quintal always 100 kg?
In modern usage, yes—the metric quintal is always 100 kg. However, historically no—pre-metric quintals ranged from 40-120 kg depending on region:
- Spanish: 46 kg
- Portuguese: 58.75 kg
- French (pre-1795): 48.95 kg
- British: 50.8 kg (112 lb) Always check context and date when encountering quintals in historical documents.
Why do Indian farmers use quintals instead of kilograms or tons?
The quintal offers a practical middle scale for farm operations:
- Too small: Tracking thousands of kilograms is cumbersome (5,000 kg vs. 50 quintals)
- Too large: Tons are too big for small farmer transactions (5 tons sounds massive vs. 50 quintals)
- Manageable numbers: Most harvests range 20-100 quintals per hectare (easy mental math)
- Traditional: India adopted quintals during metrication (1947-1960s), now culturally ingrained
- Government policy: Minimum Support Prices quoted per quintal, making it standard
What is the difference between a quintal and a hundredweight?
Metric quintal = 100 kg = 220.462 lb US hundredweight (cwt) = 100 lb = 45.36 kg British hundredweight (cwt) = 112 lb = 50.80 kg
A metric quintal is 2.2× heavier than US cwt and 1.97× heavier than British cwt. The names both mean "hundred," but refer to different base units (metric kg vs. imperial pounds).
How do you convert quintals per hectare to bushels per acre?
Step-by-step for wheat (1 bushel ≈ 27.22 kg at 60 lb/bushel):
-
Convert quintals/ha to kg/ha: Multiply by 100
- 50 q/ha = 5,000 kg/ha
-
Convert kg to bushels: Divide by 27.22 kg/bushel
- 5,000 kg ÷ 27.22 = 183.7 bushels
-
Convert hectares to acres: Divide by 2.47 acres/ha
- 183.7 bushels/ha ÷ 2.47 = 74.4 bushels per acre
Quick formula: q/ha × 0.367 ≈ bushels/acre (for wheat)
Are quintals used in the United States?
Very rarely. The US agricultural sector uses:
- Bushels for grain (wheat, corn, soybeans)
- US hundredweight (100 lb) for livestock, potatoes
- Pounds or tons (2,000 lb) for most commodities
- Metric tons for international trade
Quintals might appear in international trade documents, Latin American imports, or historical contexts, but are not part of standard US agricultural commerce.
Why is Brazilian coffee measured in 60 kg bags instead of quintals?
The 60 kg bag (0.6 quintals) became the Brazilian coffee standard due to:
- Historical Portuguese quintal: 58.75 kg ≈ 60 kg (close approximation)
- Human handling: 60 kg is about the maximum two workers can comfortably lift
- International standard: The 60 kg bag became global coffee standard adopted by other producers
- Convenient: 1,000 kg = 16.67 bags (close to 17), making mental math easier than 10 quintals
Brazilian coffee is thus priced per "saca" (60 kg bag), though sometimes converted to quintals for comparison.
How much wheat is 100 quintals in bushels?
100 quintals = 367 bushels (for wheat at 60 lb/bushel):
- 100 quintals = 10,000 kg = 22,046 pounds
- 22,046 lb ÷ 60 lb/bushel = 367.4 bushels
Alternatively:
- 10,000 kg ÷ 27.22 kg/bushel = 367.4 bushels
This represents about 15.3 acres of excellent wheat yield (24 bushels/acre × 15.3 = 367 bushels).
Do European countries still use quintals today?
Yes, but declining. Usage varies by country:
Still Common:
- France: Agricultural statistics (rendements en quintaux/hectare)
- Italy: Rural markets, traditional farming (quintale)
- Spain/Portugal: Some rural areas, older generation
- Francophone Africa: Senegal, Ivory Coast, Mali
Largely Replaced:
- Germany: Zentner (50 kg) or metric tons preferred
- UK: Fully metricated to kilograms/tonnes (1990s-2000s)
- Netherlands/Nordics: Kilograms and tonnes exclusively
Trend: Urban, industrial, and export sectors use metric tons; rural and traditional markets retain quintals.
What does "yield of 50 quintals per hectare" mean?
50 q/ha means:
- 5,000 kilograms per hectare (50 × 100 kg)
- 5 metric tons per hectare
- 2.02 metric tons per acre (÷ 2.47 acres/ha)
- 4,454 pounds per acre
Context:
- Wheat: 50 q/ha is a good yield (global average ~35 q/ha)
- Corn: 50 q/ha is low (modern varieties reach 100+ q/ha)
- Rice: 50 q/ha is moderate (high-yield areas reach 70+ q/ha)
How do I convert a price from quintals to metric tons?
Multiply by 10 (since 1 metric ton = 10 quintals):
Example 1 - Indian Wheat:
- ₹2,125 per quintal × 10 = ₹21,250 per metric ton
Example 2 - French Grain:
- €25 per quintal × 10 = €250 per metric ton
Example 3 - Brazilian Sugar:
- R$120 per quintal × 10 = R$1,200 per metric ton
Reverse (tons to quintals): Divide by 10
- $500/tonne ÷ 10 = $50 per quintal
