The liter (US spelling) or litre (International spelling) (symbol: L or l) is a metric unit of volume commonly used for measuring liquids and some bulk solids.
Official Definition: One liter is defined as exactly one cubic decimeter (1 dm³), which equals:
- 1,000 cubic centimeters (cm³)
- 0.001 cubic meters (m³)
- 1,000 milliliters (mL)
Key relationships:
- 1 liter = 1,000 milliliters (mL)
- 1 liter = 100 centiliters (cL)
- 1 liter = 10 deciliters (dL)
- 1,000 liters = 1 cubic meter (m³)
- 1 liter = 1 cubic decimeter (dm³)
In terms of US customary units:
- 1 liter ≈ 0.264172 US gallons - Convert L to gallons
- 1 liter ≈ 33.814 US fluid ounces - Convert L to fl oz
- 1 liter ≈ 4.227 US cups - Convert L to cups
- 1 liter ≈ 2.113 US pints - Convert L to pints
- 1 liter ≈ 1.057 US quarts - Convert L to quarts
Visual perspective (how much is it?):
- 1 liter ≈ Large water bottle
- 1 liter ≈ Four standard drinking glasses (250mL each)
- 1 liter ≈ About 1/4 US gallon
- 2 liters ≈ Standard soda bottle
- 5 liters ≈ Large cooking pot
- 10 liters ≈ Standard bucket
Important note: The liter is not a base SI unit (the cubic meter is), but it is accepted for use with SI units and is the most common volume measurement globally for liquids.

The US liquid quart (symbol qt US) is a unit of volume in the United States customary units system. It is equal to one-quarter of a US gallon, which is exactly 57.75 cubic inches or approximately 0.946 liters. It is commonly used for measuring medium quantities of liquids, such as milk, oil, and juices.
Precise definition:
- 1 US liquid quart = 1/4 US gallon (exactly)
- 1 US liquid quart = 32 US fluid ounces (exactly)
- 1 US liquid quart = 2 US pints (exactly)
- 1 US liquid quart = 4 US cups (exactly)
- 1 US liquid quart = 57.75 cubic inches (exactly)
- 1 US liquid quart = 946.352946 milliliters (exactly, since 1959)
- 1 US liquid quart ≈ 0.946353 liters
Relationship to metric:
- 1 liter ≈ 1.057 US quarts (about 5.7% larger)
- 1 US quart ≈ 0.946 liters (about 5.4% smaller than liter)
US Liquid Quart vs. Imperial Quart
Critical distinction for international recipes and commerce:
US Liquid Quart:
- 946.35 milliliters (0.946 L)
- Based on US gallon (231 cubic inches)
- Used in: United States
- 1/4 of US gallon (exactly)
Imperial Quart:
- 1,136.52 milliliters (1.137 L)
- Based on Imperial gallon (277.42 cubic inches)
- Used in: United Kingdom, Canada (declining), some Commonwealth nations
- 1/4 of Imperial gallon (exactly)
Size comparison:
- Imperial quart is 20% larger than US quart
- 1 Imperial quart = 1.201 US quarts
- 1 US quart = 0.833 Imperial quarts
Why this matters:
- UK recipe calling for "1 quart" = 1.137 L (need 1.2 US quarts)
- US recipe calling for "1 quart" = 0.946 L (UK needs 0.83 Imperial quarts)
- Packaged goods: Must specify which quart when importing/exporting
US Liquid Quart vs. US Dry Quart
Two different quarts in US measurement system:
US Liquid Quart:
- 946.35 milliliters (0.946 L)
- Used for liquids: milk, juice, oil, water
- 32 fluid ounces
- Most common in everyday use
US Dry Quart:
- 1,101.22 milliliters (1.101 L)
- Used for dry goods: berries, grains, produce
- 16.4% larger than liquid quart
- Rarely used (mostly replaced by weight measurements)
When you see "quart" without qualifier: Assume liquid quart (default in US)
Note: The Liter is part of the metric (SI) system, primarily used globally in science and trade. The Quart belongs to the imperial/US customary system.
History of the Liter and Quart
-
French Revolution Origins (1795): The liter was introduced in France as part of the new metric system during the revolutionary period. It was defined as the volume of one cubic decimeter (a cube 10 cm on each side), making it directly related to the meter.
-
Original Name: Initially called the "cadil," the name was quickly changed to "litron" and then simplified to "litre" (liter in US English). The name derives from an old French measurement unit.
-
Water-Based Definition (1795-1901): For a time, the liter was defined as the volume occupied by one kilogram of pure water at maximum density (approximately 4°C) and standard atmospheric pressure. This created a slight discrepancy with the cubic decimeter definition.
-
Redefinition to Cubic Decimeter (1901): The 3rd CGPM redefined the liter to be exactly equal to one cubic decimeter (1 dm³), eliminating the water-based definition and any slight variations.
-
Symbol Confusion (pre-1979): For many years, the lowercase "l" was the standard symbol for liter. However, this caused confusion with the number "1" in many fonts, especially in printed materials and handwriting.
-
Uppercase "L" Adoption (1979): At the 16th General Conference on Weights and Measures (CGPM), the uppercase "L" was officially approved as an alternative symbol to reduce confusion. Today, both "L" and "l" are acceptable, though "L" is strongly preferred in North America and becoming more common worldwide.
-
SI Status: The liter is not technically an SI base unit or derived unit. The official SI unit for volume is the cubic meter (m³). However, the liter is specifically accepted for use with the SI system due to its widespread use and convenience for everyday measurements.
-
Global Adoption: The liter became the standard unit for liquids in metric countries throughout the 19th and 20th centuries. Today it's used for:
- Beverage containers worldwide
- Fuel sales in most countries
- Cooking measurements in metric recipes
- Engine displacement (car engines)
- Medical fluid measurements
- Laboratory work
-
United States Usage: While the US primarily uses gallons for fuel and many beverages, liter bottles (1L, 2L, etc.) are standard for soft drinks, and liters are increasingly used in scientific, medical, and automotive contexts.
-
Cultural Note: The spelling "litre" is used in most English-speaking countries (UK, Canada, Australia), while "liter" is the American spelling. Both refer to the same unit.
The quart, meaning 'quarter part' (of a gallon), shares its history with the gallon. The US liquid quart is derived from the English wine gallon (231 cubic inches), making it distinct from the Imperial quart used elsewhere, which is based on the larger Imperial gallon.
Medieval Origins: The "Quarter Gallon"
Etymology and early use:
"Quart" from Latin "quartus":
- Latin: "quartus" = fourth
- Old French: "quarte" = quarter
- English: "quart" = one-fourth of a gallon
- Simple fractional relationship made it practical for trade
Medieval English liquid measures:
- Gallon: Primary large liquid unit (wine, ale, milk)
- Quart: 1/4 gallon (convenient middle size)
- Pint: 1/8 gallon (1/2 quart)
- Cup: 1/16 gallon (1/2 pint)
Why quarters were useful:
- Easy mental math: 4 quarts = 1 gallon
- Convenient container size for households
- Balanced between pint (too small for families) and gallon (too large for single use)
English Wine Gallon Standard (1707)
Queen Anne establishes wine gallon:
1707: Wine Gallon Act:
- Defined wine gallon as 231 cubic inches (exactly)
- Based on cylinder 7 inches diameter × 6 inches high
- Created to standardize wine trade across British Empire
- Wine quart = 231 ÷ 4 = 57.75 cubic inches
Why "wine" gallon:
- Separate from "ale gallon" (282 cubic inches) used for beer
- Wine gallon used for wines, spirits, and general liquids
- Eventually became standard for all liquids in American colonies
Colonial American adoption:
- American colonies used English wine gallon system
- Quart became standard for milk, cider, cooking liquids
- Taverns served drinks by the quart or pint
American Independence and Standardization (1776-1832)
US preserves wine gallon after independence:
1776-1820s: Post-independence confusion:
- No official federal standard after breaking from Britain
- States used varying interpretations of gallon/quart
- Trade disputes over measurement differences
1832: US Treasury Department standardization:
- Treasury established 231 cubic inch gallon as official US standard
- Quart = 57.75 cubic inches (1/4 gallon)
- Based on physical "gallon standard" kept in Treasury
- Applied to customs, commerce, taxation
Comparison to other measures:
- US adopted wine gallon (231 in³)
- Rejected British ale gallon and corn gallon
- Created permanent US standard independent of Britain
British Imperial Divergence (1824)
UK creates larger Imperial quart:
1824: Weights and Measures Act (UK):
- Britain replaced wine/ale gallon confusion with single Imperial gallon
- Imperial gallon = 277.42 cubic inches (10 pounds of water at 62°F)
- Imperial quart = 277.42 ÷ 4 = 69.36 cubic inches
- 20% larger than US quart
Why Britain changed:
- Wine/ale gallon system created confusion and fraud
- Wanted single standard based on water weight (metric influence)
- Scientific definition more precise than arbitrary cylinder
US did NOT follow:
- United States retained 231 cubic inch wine gallon
- Too disruptive to change established commerce
- American identity separate from British standards
- Permanent US-UK measurement split created
Result:
- US quart = 946 mL (wine gallon basis)
- Imperial quart = 1,137 mL (Imperial gallon basis)
- 20% size difference persists today
Metric Definition (1959)
Precise metric equivalent established:
July 1, 1959: International Yard and Pound Agreement:
- Defined 1 inch = exactly 25.4 millimeters
- From this: 1 cubic inch = 16.387064 cm³
- 1 US quart = 57.75 in³ × 16.387064 = 946.352946 mL (exactly)
Why this mattered:
- Ended slight US-UK inch discrepancies
- Allowed precise metric conversion
- International trade standardization
- Scientific calculations simplified
Modern Era (1960s-Present)
Metric pressure vs. quart persistence:
US resistance to metrication:
- 1975 Metric Conversion Act: Voluntary metric adoption (largely failed)
- Quart remains standard for beverages, automotive fluids, cooking
- Dual labeling common: "1 quart (946 mL)"
- No plans to eliminate quart from commerce
Other countries' metrication:
- Canada: Officially metric since 1970s, but Imperial quarts still understood
- UK: Officially metric, but pints persist for beer/milk (quarts rare)
- Australia/NZ: Fully metric, quarts obsolete
Current US usage:
- Grocery: Milk, juice, broth sold in quarts
- Automotive: Motor oil in quart bottles
- Cooking: Recipes use quarts for liquids
- Paint/adhesives: Often sold by quart
- Nurseries: Potting soil, plant containers sized in quarts

Additional Unit Information
About Liter (L)
How much is 1 liter visually?
One liter is about the volume of a large water bottle or slightly more than a quart.
Visual comparisons:
- Large water bottle: Standard 1 L bottle
- Two standard soda cans: 2 × 355 mL ≈ 0.71 L (close)
- Four standard glasses: 4 × 250 mL = 1 L
- Milk carton: Often 1 L size
- Slightly larger than a quart: 1 L = 1.057 quarts
Physical dimensions:
- A cube 10 cm × 10 cm × 10 cm = exactly 1 L
- This is the definition: 1 cubic decimeter
To remember: Picture a standard water or soda bottle - that's about 1 liter.
How many milliliters are in a liter?
There are exactly 1,000 milliliters (mL) in one liter.
Why 1,000?: The prefix "milli-" means 1/1,000.
Conversion:
- 1 liter (L) = 1,000 milliliters (mL)
- To convert L to mL: multiply by 1,000
- To convert mL to L: divide by 1,000
Examples:
- 0.5 L = 500 mL
- 1.5 L = 1,500 mL
- 2 L = 2,000 mL
- 0.25 L = 250 mL (one cup)
- 0.355 L = 355 mL (soda can)
Remember: Move the decimal point three places:
- L → mL: Move right (1.5 L = 1,500 mL)
- mL → L: Move left (500 mL = 0.5 L)
Use our liter to mL converter for instant conversions.
How many liters are in a gallon?
US gallon: 1 US gallon = 3.78541 liters (about 3.8 L) UK gallon: 1 UK gallon = 4.54609 liters (about 4.5 L)
US gallon conversion:
- 1 US gallon ≈ 3.785 liters
- 2 gallons ≈ 7.57 liters
- 5 gallons ≈ 18.93 liters
- 10 gallons ≈ 37.85 liters
Reverse (liters to US gallons):
- 1 liter ≈ 0.264 US gallons
- 4 liters ≈ 1.06 US gallons
- 10 liters ≈ 2.64 US gallons
Why two different gallons?
- US (liquid) gallon: 3.785 L
- Imperial (UK) gallon: 4.546 L
- Always specify which gallon!
Quick mental math:
- 4 liters ≈ 1 US gallon (slightly more)
- 4.5 liters ≈ 1 UK gallon
Convert: liters to gallons | gallons to liters
Is a liter exactly 1 kilogram of water?
Almost, but not exactly. For pure water at 4°C, 1 liter weighs very close to 1 kilogram, but they're different types of measurements.
The relationship:
- 1 liter of water ≈ 1 kilogram (at 4°C, maximum density)
- This is approximate, not exact definition
- Temperature affects water density slightly
Why the confusion?
- The original kilogram definition (1795) was based on 1 liter of water
- This connection was later broken when definitions were refined
- Now they're independently defined
Important distinction:
- Liter: Measures volume (space occupied)
- Kilogram: Measures mass (amount of matter)
- For water: 1 L ≈ 1 kg (convenient coincidence)
- For other liquids: Different (oil, milk, alcohol have different densities)
Examples:
- 1 L water ≈ 1 kg
- 1 L milk ≈ 1.03 kg
- 1 L olive oil ≈ 0.92 kg
- 1 L gasoline ≈ 0.74 kg
How do you convert liters to cups?
To convert liters to US cups, multiply by approximately 4.227.
Conversion formula: cups = liters × 4.22675
Examples:
- 1 liter = 4.23 cups
- 0.5 liters = 2.11 cups
- 2 liters = 8.45 cups
- 0.25 liters = 1.06 cups (about 1 cup)
Reverse conversion (cups to liters):
- 1 US cup = 0.236588 liters (about 237 mL)
- 2 cups = 0.473 liters
- 4 cups = 0.947 liters (about 1 L)
Metric recipe approximation:
- Many metric recipes use 250 mL as "1 cup"
- This makes 1 L = exactly 4 "cups"
- Simpler, but slightly different from US cup (236.588 mL)
Why 4.227?
- 1 US cup = 236.588 mL (official)
- 1,000 mL ÷ 236.588 mL/cup = 4.227 cups
Use our liter to cups converter for precise conversions.
What is the difference between L and l for liter?
No difference in measurement - both symbols represent the same unit, one liter.
Symbol variations:
- L (uppercase): Officially approved in 1979, preferred
- l (lowercase): Original symbol, still valid
- Both are correct and mean exactly the same thing
Why the uppercase "L"?
- Lowercase "l" looks like number "1" in many fonts
- Created confusion in medical prescriptions and recipes
- 1979: CGPM approved uppercase "L" to reduce errors
- Especially important for handwriting
Current practice:
- North America: Almost exclusively uses "L"
- Europe: Mixed usage, both "L" and "l" common
- Scientific papers: Increasingly using "L"
- Medical field: Strongly prefers "L" for safety
Other symbols (not standard):
- "ℓ" (script L): Sometimes used but not official
- "lt" or "ltr": Abbreviations, not official symbols
Remember: Whether you see "L" or "l," it's the same measurement - one liter.
How many liters should I drink per day?
General recommendation: 2-3 liters (8-12 cups) of total fluids per day for adults.
Specific recommendations:
- Women: ~2.7 liters (11 cups) total fluids per day
- Men: ~3.7 liters (15 cups) total fluids per day
- Includes: Water, beverages, food moisture
Water intake specifically:
- Women: ~2-2.2 liters of plain water
- Men: ~2.5-3 liters of plain water
- "8×8 rule": 8 glasses of 8 oz = ~1.9 liters (minimum)
Factors that increase needs:
- Exercise and sweating
- Hot weather
- Illness (fever, vomiting, diarrhea)
- Pregnancy (2.3 L) or breastfeeding (3.1 L)
- High altitude
- High-fiber diet
Factors that decrease needs:
- High water-content foods (fruits, vegetables)
- Other beverages (tea, coffee, juice)
- Cold weather
- Sedentary lifestyle
Signs of adequate hydration:
- Pale yellow urine
- Urinating every 2-4 hours
- Not feeling thirsty
Remember: Individual needs vary - listen to your body and drink when thirsty.
How do you convert liters to fluid ounces?
To convert liters to US fluid ounces, multiply by approximately 33.814.
Conversion formula: fl oz = liters × 33.814
Examples:
- 1 liter = 33.8 fl oz
- 0.5 liters = 16.9 fl oz (small water bottle)
- 2 liters = 67.6 fl oz (large soda bottle)
- 0.355 liters = 12 fl oz (soda can)
Reverse conversion (fl oz to liters):
- 1 US fl oz = 0.0296 liters (29.57 mL)
- 8 fl oz (1 cup) = 0.237 liters
- 16 fl oz (1 pint) = 0.473 liters
- 32 fl oz (1 quart) = 0.946 liters
UK vs US fluid ounce:
- US fluid ounce: 29.57 mL
- UK (imperial) fluid ounce: 28.41 mL
- Slightly different!
Why 33.814?
- 1 liter = 1,000 mL
- 1 US fl oz = 29.5735 mL
- 1,000 ÷ 29.5735 = 33.814 fl oz
Use our liter to fluid ounce converter for accurate conversions.
What is 2 liters in ounces?
2 liters = 67.628 US fluid ounces (commonly rounded to 67.6 fl oz or 68 fl oz).
Calculation: 2 L × 33.814 fl oz/L = 67.628 fl oz
Common context:
- 2 L soda bottle: Standard large bottle size
- Just over 2 quarts: 2 L = 2.11 quarts
- Just over half gallon: 2 L = 0.528 US gallons
- About 8.5 cups: 2 L = 8.45 cups
Related conversions:
- 1 L = 33.8 fl oz
- 1.5 L = 50.7 fl oz
- 2 L = 67.6 fl oz
- 2.5 L = 84.5 fl oz
- 3 L = 101.4 fl oz
Visual reference:
- Standard soda bottle = 2 L = 67.6 fl oz
- Two 1 L bottles = 2 L
- Eight 8 oz glasses + a little more = 2 L
Convert any volume: liters to fl oz converter
Is the liter an SI unit?
Technically no, but yes for practical purposes.
Official status:
- Not a base SI unit: The official SI unit for volume is the cubic meter (m³)
- Accepted for use with SI: The liter is specifically approved for use alongside SI units
- Widely used: The liter is far more common than cubic meters for everyday measurements
Why it's accepted:
- Defined in SI terms: 1 L = 1 dm³ = 0.001 m³
- Decimal-based like all SI units
- Convenient size for everyday use
- Avoids awkward decimals (0.001 m³ vs 1 L)
Historical note:
- Originally defined as metric unit in 1795
- Kept when SI was established in 1960
- Given special status due to widespread use
In practice:
- Scientists use liters routinely (especially chemistry)
- Cubic meters used for large volumes (rooms, tanks)
- Cubic centimeters (= mL) used for small volumes
- Liter fills the practical middle ground
Remember: While not technically an SI base unit, the liter is fully compatible with and accepted for use with the SI system.
How many liters in a cubic meter?
There are exactly 1,000 liters in one cubic meter.
Conversion:
- 1 cubic meter (m³) = 1,000 liters (L)
- 1 liter = 0.001 cubic meters (or 1/1,000 m³)
Why 1,000?
- 1 liter = 1 cubic decimeter (dm³)
- 1 meter = 10 decimeters
- 1 m³ = 10 × 10 × 10 dm³ = 1,000 dm³ = 1,000 L
Examples:
- 0.5 m³ = 500 liters
- 2 m³ = 2,000 liters
- 0.001 m³ = 1 liter
- 50 m³ = 50,000 liters (small swimming pool)
Practical uses:
- Swimming pool: 50 m³ = 50,000 L
- Water tank: 2 m³ = 2,000 L
- Aquarium: 0.5 m³ = 500 L
- Room volume: Calculate in m³, not liters
When to use which:
- Liters: Liquids, containers, bottles (< 1,000 L)
- Cubic meters: Large volumes, rooms, pools, tanks (> 1,000 L)
Convert: liters to m³ | m³ to liters
About Quart (qt)
How many pints are in a US quart?
There are exactly 2 US liquid pints in 1 US liquid quart. This is a fundamental relationship: quart = 2 pints, pint = 1/2 quart. For example, a quart of milk equals two pint-sized servings.
How many cups are in a US quart?
There are exactly 4 US customary cups in 1 US liquid quart. This is one of the most useful kitchen conversions: 1 quart = 4 cups = 32 fluid ounces. For cooking, remember that doubling a 2-cup measurement gives you 1 quart.
Is a US quart the same as an Imperial quart?
No. The US liquid quart (≈ 0.946 L) is about 20% smaller than the Imperial quart (≈ 1.137 L). The US quart is based on the wine gallon (231 cubic inches ÷ 4), while the Imperial quart is based on the larger Imperial gallon (277.42 cubic inches ÷ 4). When using British or Canadian recipes, you must convert: 1 Imperial quart = 1.2 US quarts.
How many fluid ounces are in a quart?
There are exactly 32 US fluid ounces in 1 US liquid quart. This is standard across all liquid measurements: milk cartons, broth containers, and juice bottles labeled "1 quart" contain 32 fl oz. Remember: 8 oz = 1 cup, 16 oz = 1 pint, 32 oz = 1 quart, 128 oz = 1 gallon.
How many quarts are in a gallon?
There are exactly 4 quarts in 1 US gallon. The word "quart" literally means "quarter" (of a gallon). This makes gallon-to-quart conversion easy: 1 gallon = 4 quarts, half-gallon = 2 quarts, quarter-gallon = 1 quart.
Is a quart bigger than a liter?
No, a US quart (946 mL) is slightly smaller than a liter (1,000 mL) by about 5.4%. Think of it this way: 1 liter = 1.057 quarts (about 5.7% more). For rough estimates, you can approximate 1 quart ≈ 1 liter, but for precision cooking or measurements, use the exact conversion: 1 qt = 0.946 L.
Why is motor oil sold in quarts?
Motor oil is sold in quarts because most engine oil capacities are 4-6 quarts, making quart bottles convenient for oil changes and top-ups. The quart size prevents overfilling (adding a full gallon would be too much) and allows mechanics and car owners to add exactly the amount needed. This standard has persisted for over a century in the automotive industry. Most oil change intervals involve draining the old oil and adding 4-5 individual quart bottles.
What is a dry quart?
A dry quart is a separate US measurement (1.101 liters) used for measuring dry goods like berries, grains, and produce, about 16% larger than the liquid quart (0.946 L). However, dry quarts are rarely used today—most dry goods are sold by weight (pounds/ounces or grams/kilograms) rather than volume. When you see "quart" in everyday use, it almost always refers to the liquid quart. Historical note: Farmers' markets occasionally sell berries by the "dry quart" basket.
How many quarts in a 2-liter soda bottle?
A 2-liter soda bottle contains approximately 2.11 US quarts. To convert liters to quarts, multiply by 1.057: 2 L × 1.057 = 2.114 quarts. This is slightly more than 2 quarts (which would be 1.89 liters). For comparison: 1 quart = 946 mL, so 2 quarts = 1.89 L, meaning the 2-liter bottle has about 110 mL (4 oz) extra.
Can I use a quart jar for canning?
Yes, quart-sized Mason jars (32 oz) are standard for home canning and preserving. They're ideal for pickles, tomatoes, jams, sauces, and preserved fruits/vegetables. Canning recipes often specify yields in quarts (e.g., "makes 6 quarts"). Make sure to use proper canning procedures with tested recipes, as jar size affects processing time. Ball and Kerr make standardized quart canning jars designed to withstand boiling water bath or pressure canning.
Why do recipes use quarts instead of liters?
Recipes in the United States use quarts because the US has not adopted the metric system for everyday measurements. Quarts align with other US customary units (cups, pints, gallons) used in American cookbooks, measuring cups, and kitchen tools. Converting recipes to metric would require replacing all standard US measuring equipment. While professional chefs and bakers increasingly use weight (grams), home cooks still predominantly use volume measurements like quarts, cups, and tablespoons.
