Unit Conversion

Convert volume units: liters, gallons, pints, and cubic meters

The volume converter converts between metric volume units (milliliter, liter, cubic centimeter, cubic meter, microliter, nanoliter) and US volume units (gallon, quart, pint, fluid ounce, cubic foot) as well as the UK gallon. It's used equally in cooking, chemistry, and tank volume calculations.

Key conversion factors:

  • 1 liter (l) = 1,000 milliliters (ml) – standard unit for liquids
  • 1 cubic meter (m³) = 1,000 liters – common for large volumes like pools or tanks
  • 1 cubic foot (ft³) ≈ 28.32 liters – common in US/UK construction
  • 1 US gallon (gal (US)) = 3.785 liters – standard fuel measure in the US
  • 1 UK gallon (gal (UK)) = 4.546 liters – British gallon, larger than the US version
  • 1 US quart (qt (US)) = 0.946 liters – a quarter of a US gallon
  • 1 US pint (pt (US)) = 0.473 liters – an eighth of a US gallon
  • 1 US fluid ounce (fl oz (US)) = 29.57 milliliters – for small liquid amounts

Applications:

  • Cooking: converting US recipe units (pint, quart, fluid ounce) to milliliters
  • Fuel consumption: comparing tank volumes between gallons and liters
  • Chemistry & lab: exact volume dosing of solutions in micro- and nanoliters
  • Construction: calculating concrete and excavation volumes in cubic meters and cubic feet

Whether for international recipes, fuel cost comparisons, or precise lab volumes – the volume converter delivers exact results in every case. For concentrations rather than pure volumes, use the mass concentration converter or molar concentration converter.


Frequently asked questions about converting volume

1 US gallon (gal (US)) equals 3.785 liters. The UK gallon is noticeably larger at 4.546 liters – good to know when comparing fuel consumption between US and UK figures, for example.

1 US quart (qt (US)) equals 0.946 liters and is twice as large as 1 US pint (pt (US)) at 0.473 liters. Both are fractions of the US gallon: 1 gallon = 4 quarts = 8 pints.

Yes, 1 cubic centimeter (cm³) equals exactly 1 milliliter (ml) – both units are identical by definition and are used differently depending on the field (cm³ more in engineering and medicine, ml more in everyday life and chemistry).
