The metric ton (or tonne, symbol: t) is a unit of mass equal to 1,000 kilograms (kg). It is part of the International System of Units (SI) - although not technically a base SI unit itself, it is accepted for use with SI. It is equivalent to approximately 2,204.6 pounds.
Key relationships:
- 1 metric ton = 1,000 kilograms (kg)
- 1 metric ton = 1,000,000 grams (g)
- 1 metric ton ≈ 2,204.62 pounds (lb)
- 1 metric ton ≈ 1.10231 US tons (short tons)
- 1 metric ton ≈ 0.984207 UK tons (long tons)
Important distinction:
- Metric ton (tonne): 1,000 kg = 2,204.6 lb
- US ton (short ton): 2,000 lb = 907.185 kg
- UK ton (long ton): 2,240 lb = 1,016.05 kg

The milligram (mg) is a unit of mass in the metric system equal to one-thousandth of a gram (1/1,000 g) or one-millionth of a kilogram (1/1,000,000 kg). It represents an extremely small quantity of mass, making it the preferred unit for measuring precise amounts of medications, nutrients, chemicals, and other substances where accuracy is paramount.
The milligram is part of the International System of Units (SI) and serves as a critical measurement standard in medicine, pharmacology, chemistry, nutrition science, and precision manufacturing. Its small scale allows for expressing tiny quantities without resorting to decimal fractions of grams, providing clarity and reducing the risk of measurement errors that could have serious consequences in medical and scientific applications.
Note: The Ton (metric) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Milligram belongs to the metric (SI) system.
History of the Ton (metric) and Milligram
-
Etymology: The term "tonne" derives from the "tun", an old English unit of volume for large casks used in wine and beer trade. The word evolved through French ("tonneau") before being adapted for the metric system.
-
Metric System Development: The metric ton was defined as 1,000 kilograms to provide a larger, practical metric unit for commerce, trade, and industry. This maintained the decimal nature of the metric system while providing a convenient unit for heavy goods.
-
Why 1,000 kg?: The choice aligned with the metric prefix system:
- 1 gram = base unit for daily use
- 1 kilogram = 1,000 grams (convenient for everyday weighing)
- 1 metric ton = 1,000 kilograms (convenient for heavy industry)
-
International Adoption: As countries adopted the metric system throughout the 19th and 20th centuries, the metric ton became the standard for international trade, shipping, and industrial production.
-
SI Acceptance: When the International System of Units (SI) was established in 1960, the metric ton was accepted for use with SI units as a practical multiple of the kilogram (the SI base unit of mass).
-
Spelling Variations:
- "Tonne" is the international spelling (French origin)
- "Metric ton" is used in the US to distinguish from US/UK tons
- Both refer to the same unit: 1,000 kg
-
Modern Usage: Today, the metric ton is the global standard in shipping, international trade, agriculture, mining, and most industrial applications. Only a few countries (primarily the US) still use non-metric tons for domestic purposes.
The milligram emerged as a practical subdivision of the gram when the metric system was formalized in France in the late 18th century. While the kilogram was established as the base unit of mass in 1795, scientists and physicians quickly recognized the need for much smaller units to measure chemicals, medicines, and biological samples.
The term "milligram" combines the Latin prefix "milli-" (meaning one-thousandth) with "gram," creating a logical decimal relationship that simplified calculations and conversions. This standardization was revolutionary—before the metric system, apothecaries used confusing units like grains, scruples, and drams, which varied by region and led to dangerous medication errors.
The importance of the milligram grew dramatically during the 19th century as pharmaceutical science advanced. The ability to precisely measure active ingredients in medications became critical for patient safety. By the early 20th century, the milligram had become the global standard for drug dosing, appearing on prescription labels, medication packaging, and medical literature worldwide.
The 1960 formalization of the International System of Units (SI) cemented the milligram's status as an official metric unit, though it's technically a submultiple of the kilogram rather than a base unit itself. Today, the milligram remains indispensable in healthcare, with virtually every pharmaceutical product worldwide labeled in milligrams.

Convert between them: Metric ton to US ton | Ton to pound
Why is it sometimes spelled "tonne"?
"Tonne" is the international spelling used to clearly distinguish the metric ton from imperial/US tons (short ton and long ton).
Usage:
- "Tonne": International standard, used in UK, Australia, Europe, Asia
- "Metric ton": Used in the United States to distinguish from US ton
- Both refer to the same unit: 1,000 kilograms
Pronunciation: Same pronunciation for both ("tun")
Why different spellings exist:
- Avoids confusion with short ton (US) and long ton (UK)
- "Tonne" comes from French ("tonneau")
- Makes documentation clearer in international trade
- Some industries prefer one spelling over the other
In practice: Use "metric ton" in US contexts, "tonne" elsewhere, or specify "1,000 kg" to be absolutely clear.
How many pounds are in a metric ton?
1 metric ton = 2,204.62 pounds (lb)
Commonly rounded to 2,205 pounds for practical use.
Conversion:

How do you convert cubic meters to metric tons?
You can't directly convert - cubic meters (m³) measure volume, metric tons (t) measure mass. You need to know the density of the material.
Formula: Mass (tons) = Volume (m³) × Density (tons/m³)
Common Material Densities:
Liquids:
- Water: 1 m³ = 1 ton (exactly, at 4°C)
- Gasoline: 1 m³ = 0.75 ton
- Diesel: 1 m³ = 0.85 ton
- Crude oil: 1 m³ = 0.8-0.95 ton
- Milk: 1 m³ = 1.03 ton
Construction Materials:
- Concrete: 1 m³ = 2.4 ton
- Asphalt: 1 m³ = 2.3 ton
- Gravel: 1 m³ = 1.5-1.7 ton
- Sand (dry): 1 m³ = 1.6 ton
- Topsoil: 1 m³ = 1.2-1.4 ton
Metals:
- Steel: 1 m³ = 7.85 ton
- Aluminum: 1 m³ = 2.7 ton
- Copper: 1 m³ = 8.96 ton
- Gold: 1 m³ = 19.3 ton
Wood (varies greatly):
- Softwood: 1 m³ = 0.4-0.6 ton
- Hardwood: 1 m³ = 0.6-0.9 ton
Example: How many tons is 10 m³ of concrete?
- 10 m³ × 2.4 tons/m³ = 24 metric tons
Tip: Always check the specific material's density for accurate conversion.
How many metric tons can a truck carry?
It varies widely by truck type and regulations:
Light Trucks:
- Pickup truck (half-ton): 0.5-1 ton payload
- Pickup truck (one-ton): 1-1.5 ton payload
- Cargo van: 1-1.5 ton
- Small box truck: 1-2 ton
Medium Trucks:
- Medium box truck: 3-5 ton
- Large delivery truck: 5-8 ton
- Flatbed truck: 8-12 ton
- Dump truck: 10-15 ton
Heavy Trucks (Semi-trucks):
- Typical semi-truck: 20-25 ton payload
- Maximum legal (US): ~23 ton (gross weight 36 ton)
- Maximum legal (Europe): ~26 ton (gross weight 40-44 ton)
- Special permit: Up to 40+ ton (overweight permits)
Specialized:
- Mining dump truck: 100-400 ton
- Logging truck: 20-30 ton
- Concrete mixer: 8-10 ton of concrete
- Tanker truck: 20-30 ton of liquid
Legal Limits Vary By:
- Country/region regulations
- Road type (highway vs local)
- Number of axles
- Permits (standard vs overweight)
Note: These are payload capacities (cargo weight), not including the truck's own weight.
What is the difference between gross ton and net ton?
Gross Ton and Net Ton refer to different measurement contexts:
In Shipping:
Gross Tonnage (GT):
- Measures a ship's overall internal volume
- NOT weight - despite "tonnage" in the name!
- Used for registration, regulations, port fees
- Formula based on enclosed spaces
- Example: Cruise ship = 100,000 GT
Net Tonnage (NT):
- Measures a ship's earning capacity (cargo space volume)
- Also volume, not weight
- Excludes crew quarters, machinery, etc.
- Example: Same cruise ship = 50,000 NT
In Mining/Refining:
Gross Ton:
- Total weight including impurities
- Example: Iron ore with rock mixed in
Net Ton:
- Pure/usable material weight
- Example: Pure iron content only
In Commerce:
Gross Weight:
- Total weight including packaging, container
- Example: Product + box + pallet = gross weight
Net Weight:
- Product weight only (excluding packaging)
- Example: Just the product itself
Important: In most shipping contexts, "tonnage" refers to volume, not weight. For actual cargo weight, use "deadweight tonnage (DWT)" in metric tons.
How much is a ton of CO₂?
1 ton of CO₂ is a measurement used in climate science and carbon accounting. But what does it mean practically?
Visual Understanding (CO₂ is a gas, so it's about volume):
- 1 ton of CO₂ at normal pressure = ~509 cubic meters of gas
- That's a cube about 8 meters on each side (26 feet)
- Enough to fill a small house!
How Much Do We Emit?
Individual Activities:
- Driving: 1 ton CO₂ = ~2,500 miles in average car
- Flying: 1 ton CO₂ = ~1 passenger, economy, transatlantic flight
- Electricity: 1 ton CO₂ = ~1,700 kWh (varies by power source)
- Natural gas heating: 1 ton CO₂ = ~500 therms
Average Annual Emissions:
- US person: ~16 tons CO₂/year
- Europe person: ~6-8 tons CO₂/year
- Global average: ~4 tons CO₂/year
- Target (Paris Agreement): ~2 tons CO₂/year by 2050
To Offset 1 Ton of CO₂:
- Plant ~50-100 trees (over their lifetime)
- Avoid ~1,000 miles of driving
- Switch to renewable energy for several months
- Reduce meat consumption significantly
Cost of Carbon:
- Carbon credits: $10-50 per ton (varies by market)
- Carbon tax: Varies by country
- Offset programs: $10-30 per ton typically
Why It Matters: Understanding ton of CO₂ helps track climate impact, set reduction goals, and calculate carbon footprints.
How many metric tons is a shipping container?
Container Weight Depends on Type and Loading:
Empty Container Weight:
- 20-ft container: 2.3 metric tons (empty)
- 40-ft container: 3.7 metric tons (empty)

Volume vs Weight:
- Container volume: 20-ft = 33 m³, 40-ft = 67 m³
- If cargo is light: Volume fills before weight limit
- If cargo is dense: Weight limit reached before volume fills
Example:
- Container full of styrofoam: ~5 tons (volume limited)
- Container full of steel plates: ~28 tons (weight limited)
TEU = Twenty-foot Equivalent Unit (shipping industry standard):
- 1 TEU = One 20-ft container
- 1 FEU = One 40-ft container = 2 TEU

About Milligram (mg)
How many milligrams are in a gram?
There are exactly 1,000 milligrams (mg) in one gram (g). This is a defined relationship in the metric system. The prefix "milli-" always means one-thousandth, so a milligram is one-thousandth of a gram.
To convert:
- Grams to milligrams: multiply by 1,000
- Milligrams to grams: divide by 1,000
Example: 3.5 g = 3,500 mg
How many milligrams are in a kilogram?
There are 1,000,000 (one million) milligrams in one kilogram. Since 1 kg = 1,000 g and 1 g = 1,000 mg, we multiply: 1,000 × 1,000 = 1,000,000 mg.
This large conversion factor is why kilograms are never used for medications—the numbers would be unwieldy. A 500 mg tablet would be "0.0005 kg," which is impractical and error-prone.
Convert milligrams to kilograms →
Is a milligram the same as a microgram?
No! A milligram (mg) is 1,000 times larger than a microgram (mcg or μg). This is one of the most dangerous medication errors in healthcare.
- 1 milligram (mg) = 1,000 micrograms (mcg)
- 1 microgram (mcg) = 0.001 milligrams (mg)
Some medications like levothyroxine, folic acid, and vitamin B12 are dosed in micrograms because the active doses are extremely small. Always verify which unit is intended, as confusing them can cause a 1,000-fold overdose or underdose.
Convert micrograms to milligrams →
What does "mg" stand for?
"mg" is the internationally recognized abbreviation for milligram. The "m" represents the metric prefix "milli-" (meaning 1/1,000), and "g" stands for gram. Together, "mg" means one-thousandth of a gram.
This abbreviation is standardized worldwide by the International System of Units (SI) and is understood across all languages and countries. Never use "mgs" with an "s"—the plural of "mg" is still "mg" (e.g., "500 mg," not "500 mgs").
How much does a milligram weigh in everyday terms?
A milligram is extremely light—almost imperceptible to human senses:
- 1 mg ≈ weight of a very small grain of sand
- 10 mg ≈ weight of a small feather fiber
- 100 mg ≈ weight of a single drop of water
- 1,000 mg = 1 gram = weight of a small paperclip
For comparison, a U.S. dollar bill weighs about 1 gram (1,000 mg), so 1 mg is 1/1,000th the weight of a dollar bill. Most household scales cannot accurately measure milligrams—you need a laboratory analytical balance.
Are milligrams used for measuring liquids?
Milligrams measure mass (weight), not volume. However, liquid medications are often prescribed in milligrams of the active ingredient, then measured in milliliters (mL) based on the concentration.
Example: A prescription might call for "500 mg of amoxicillin." If the bottle says "250 mg/5 mL," you'd measure 10 mL of the liquid to get 500 mg of the drug.
The key is understanding concentration: mg/mL tells you how many milligrams of active ingredient are in each milliliter of liquid.
Learn about medication concentrations →
How do I convert milligrams to ounces or pounds?
For converting between metric (mg) and imperial (oz, lb) units:
Milligrams to ounces:
- 1 ounce = 28,349.5 mg
- To convert mg to oz: divide mg by 28,349.5
Example: 50,000 mg ÷ 28,349.5 = 1.76 oz
Milligrams to pounds:
- 1 pound = 453,592 mg
- To convert mg to lb: divide mg by 453,592
Example: 100,000 mg ÷ 453,592 = 0.22 lb
These conversions are rarely used for medications (which stay in mg) but appear in industrial, commercial, or international shipping contexts.
Convert milligrams to ounces → Convert milligrams to pounds →
What is the difference between mass and weight when measuring milligrams?
Technically, mass is the amount of matter in an object (measured in mg, g, kg), while weight is the force of gravity on that mass. In everyday use and in medicine, these terms are used interchangeably, and we say "weight" when we mean "mass."
For practical purposes at Earth's surface, the distinction doesn't matter. A 500 mg tablet has 500 mg of mass and "weighs" 500 mg. The only time it matters is in scientific contexts involving gravity variations (like space) or high-precision physics experiments.
In medicine, pharmacy, and nutrition, "milligrams" always refers to mass, which is constant regardless of location or gravity.
Can I measure milligrams accurately at home?
Measuring true milligrams at home is challenging because most household scales lack sufficient precision:
Typical household scales:
- Kitchen scales: accurate to ±1-5 grams (not useful for mg)
- Food scales: accurate to ±0.1 grams = ±100 mg (limited use)
- Jewelry/pocket scales: accurate to ±0.01 g = ±10 mg (better, but still limited)
What you need for accurate mg measurements:
- Laboratory analytical balance: accurate to ±1 mg or ±0.1 mg
- Cost: $200-$2,000+ depending on precision
- Environment: Requires stable surface, no air currents, calibrated regularly
For medications: Never attempt to divide, measure, or adjust milligram doses at home without consulting a healthcare provider. Use pre-measured doses from pharmacies, and use provided measuring devices (syringes, droppers, cups) that are calibrated for the specific medication.
Learn about weight measurement tools →
Why are medications measured in milligrams instead of grams?
Milligrams are the standard for medications because most therapeutic doses fall conveniently between 1 mg and 1,000 mg, making the numbers practical to read and write without decimals:
- Easier to read: "500 mg" is clearer than "0.5 g"
- Reduces decimal errors: Writing "250 mg" prevents mistakes from misplaced decimal points in "0.250 g"
- International standard: The entire global pharmaceutical industry uses mg, ensuring consistency
- Appropriate scale: Most drug doses require precision at the milligram level
For very potent drugs requiring smaller amounts, micrograms (mcg) are used instead. For substances requiring larger amounts (like some electrolyte solutions), grams are used.

How do milligrams relate to "mg/kg" dosing in medicine?
Many medications are dosed based on body weight using mg/kg (milligrams per kilogram). This adjusts the dose proportionally to patient size, which is especially important for children, neonates, and certain drugs with narrow therapeutic windows.
How it works:
- Patient weight is measured in kilograms
- Prescribed dose is given as mg/kg (e.g., "5 mg/kg")
- Total dose = weight (kg) × dose (mg/kg)
Example:
- Patient weighs 60 kg
- Drug dose: 10 mg/kg
- Total dose: 60 kg × 10 mg/kg = 600 mg
This ensures safe, effective dosing regardless of whether the patient is a 3 kg newborn or a 100 kg adult.
