Volume Converter
Convert volume between mL, L, gal, qt, pt, cup, fl oz, m³, cm³ units.
Input Information
Result
Volume Converter provides accurate conversions between various volume and capacity units. You can quickly convert between milliliters (mL), liters (L), gallons (gal), quarts (qt), pints (pt), cups, fluid ounces (fl oz), cubic meters (m³), and cubic centimeters (cm³).
Volume unit conversion is frequently needed in cooking and baking, chemistry experiments, engineering design, logistics, and daily life. It is used when switching between metric and imperial units for recipe scaling, reagent mixing, tank capacity calculations, and more.
For chefs and researchers, it serves as a measuring tool. For engineers and logistics personnel, it is a design and transportation tool. Accurate volume conversion is a key factor that determines the reliability and safety of mixing ratios.
Conversion coefficients follow international standards: 1 L = 1,000 mL = 1,000 cm³, 1 m³ = 1,000 L. However, note that the US gallon (3.78541 L) and the imperial gallon (4.546 L) differ.
Term Glossary
- Gallon Types (US/Imp gal)
- US gallon is 3.78541 L and imperial gallon is 4.546 L, a difference of about 20%. Always check the gallon type in overseas documents first.
- Fluid Ounce (fl oz)
- An ounce for measuring volume, different from the mass unit ounce (oz). 1 fl oz = 29.5735 mL, mainly used for US cooking and beverage volumes.
- Choose the input unit to convert from. (L, mL, gallon, cup, etc.)
- Enter the value you want to convert.
- Choose the output unit to convert to.
- Run the conversion and results in all units are shown automatically.
1 gallon → L
1 US gallon is approximately 3.785 liters (L). It is often used for vehicle fuel capacity.
1 L → mL / cup
1 liter is 1,000 mL and approximately 4.227 cups. This is a common cooking conversion.
500 mL → L
500 milliliters is 0.5 liters. This is a common size for water bottles and beverages.
Volume Unit Conversion Relationships
Calculation Example
Converting 2 L to US gallons:
2 L ÷ 3.78541 = 0.528 gal
Volume in Cooking
- Korean cooking uses mL·L, while Western cooking uses cups·tablespoons·teaspoons.
- 1 cup ≈ 236.5 mL, 1 tbsp ≈ 15 mL.
Everyday Volume Comparisons
- Pet bottle drink: 500 mL, Water bottle: 2 L
- Bathtub: approx. 150~200 L, Small swimming pool: approx. 50,000~100,000 L
Fuel Related
- Vehicle fuel is indicated in L or gal units.
- The US uses gal, while Europe and Korea primarily use L.
Chemistry Experiments
- Measure reagent mixtures precisely in mL·L units.
- Avoid mid-scale markings considering container scale errors.
Gallon Type Caution
- US gal and Imp gal differ by about 20%.
- Always check the gallon type in overseas documents first.
Volume and Mass
- Water is approximately 1 mL = 1 g, but other liquids have different densities.
- Do not confuse volume and mass when calculating concentration.
QHow do liters and gallons differ?
The liter is the metric unit of volume while the gallon is the imperial unit of volume. One US gallon is about 3.785 liters.
QWhat is the relationship between milliliters (mL) and cubic centimeters (cc)?
1 mL is exactly equal to 1 cc (cubic centimeter, cm³). The two units are used interchangeably in medical syringes and engine displacement.
QHow do cooking measurements like cup, tablespoon, and teaspoon work?
1 cup is about 236.6 mL, 1 tablespoon (tbsp) is about 14.8 mL, and 1 teaspoon (tsp) is about 4.9 mL. These are common in cooking recipes.
QHow do US and UK gallons differ?
The US gallon is about 3.785 liters while the UK (imperial) gallon is about 4.546 liters. The values differ by about 20%, so use the unit matching the country.
QAre fluid ounces (fl oz) and ounces (oz) the same?
No. Fluid ounces (fl oz) measure volume while ounces (oz) measure weight. For example, 1 fl oz of water is about 29.57 mL, but the weight varies by substance.
