Convert recipe volume from cups to millilitres
Input
2 US cupsOutput
473 mL · 0.473 L · 16 fl oz2 cups of liquid = 473 mL. Most international recipes use mL; US recipes use cups. 1 US cup = 236.6 mL.
Convert between volume units instantly.
Kitchen cups, fuel pumps, lab glassware, and shipping cubes use different “liter” habits—check which standard you mean.
All rows reconcile through Liter internally (14 units).
The Gallon row uses the US liquid gallon (≈ 3.785 L). UK/imperial gallons are larger (~4.546 L). If a British recipe says “per gallon,” mentally swap systems before trusting a US-gallon conversion.
Cup, tablespoon, and teaspoon rows follow US customary definitions used in many American recipes. Other countries define different cup sizes (metric cup ≈ 250 mL, Japanese rice cup ≈ 180 mL). For baking precision, weigh ingredients or confirm which cup standard the author used.
The barrel value here follows the common petroleum barrel conversion (~159 L) used in energy and commodity contexts—not every industry barrel (beer, wine, shipping) shares the same volume, so always confirm the contract spec.
This tool’s gallon is the US liquid gallon (~3.785 L). A UK/imperial gallon is about 4.546 L—roughly 20% larger. If you are pricing paint in London or reading an old British cookbook, sanity-check which gallon they mean before trusting a straight US conversion.

Choose your unit: litres, millilitres, cubic metres, cubic centimetres (= mL), US gallons, UK gallons, US fluid ounces, US cups, US pints, US quarts, or cubic feet.
All equivalents appear at once. For cooking, the cup/tablespoon/teaspoon values are most useful. For industrial use, cubic metres or litres.

56.78 litres · 56,781 mL · 12.49 UK gallonsUS car fuel tanks are measured in US gallons; European equivalents use litres. A 15-gallon tank holds 56.8 litres. Note: US and UK gallons are different.
Common real-world scenarios where this tool saves time.
Home cooks and recipe followers
US recipes use cups; international recipes use mL or grams for liquids. Accurate volume conversion prevents measurement errors that affect recipe outcomes, especially in baking.
Chemists and lab scientists
Lab protocols specify volumes in mL or µL; storage tanks are measured in litres or m³. Accurate conversion between scales prevents dosing and dilution errors.
Travellers and drivers
Fuel prices in the US are per US gallon; in Europe per litre. Converting fuel prices to a common unit allows direct price comparison: $4/gallon = $1.06/litre.

1 US cup = 236.588 mL. Common cup fractions: ½ cup = 118.3 mL, ⅓ cup = 78.9 mL, ¼ cup = 59.1 mL. Note: metric cups (used in Australia, Canada) = 250 mL — slightly larger than the US cup.
1 US gallon = 3.78541 litres. 1 UK (imperial) gallon = 4.54609 litres. The US and UK gallons are different — the UK gallon is about 20% larger. A 10 US gallon gas can holds 37.85 litres.
1 US fluid ounce = 29.5735 mL. 1 UK (imperial) fluid ounce = 28.4131 mL. They are close but not identical. Most international recipes and nutritional labels use mL to avoid this ambiguity.
1 litre = 4.2268 US cups. Approximate: 1 litre ≈ 4 cups + 3 tablespoons. For cooking, 1 litre = 4 cups is a common enough approximation. 2 litres ≈ 8.5 cups.
1 litre = 1,000 cubic centimetres (cm³). This is exact by definition. 1 cm³ = 1 mL. So 250 mL = 250 cm³. The cubic centimetre and millilitre are numerically identical for liquid volume.
