About the Volume Converter

Volume measures the amount of three-dimensional space an object or substance occupies. The metric system uses litres and millilitres for everyday quantities, and cubic metres for larger volumes. The imperial and US customary systems use gallons, pints, cups, and fluid ounces — which differ between the US and UK.

This converter covers 15 units from teaspoons to oil barrels, handling cooking, fuel, chemistry, and industrial applications in one place.

SI base unit	Cubic metre (m³)
1 litre	1,000 mL / 0.001 m³
1 US gallon	3.785 L / 3,785 mL
1 UK gallon	4.546 L (20% larger)
1 US cup	236.588 mL
1 oil barrel	158.987 L

Frequently Asked Questions

Both spellings are correct. \u201cLitre\u201d is the standard in British English and most of the world. \u201cLiter\u201d is the American English spelling. The SI symbol is L in both cases.

A US gallon equals 3.785 litres, while a UK (imperial) gallon equals 4.546 litres. The UK gallon is about 20% larger than the US gallon. Always check which system a recipe or fuel rating uses.

There are approximately 4.227 US cups in one litre. A US cup equals 236.588 mL, so 1,000 mL \u00f7 236.588 = 4.227 cups.

To convert millilitres to US fluid ounces, divide by 29.5735. For example, 500 mL \u00f7 29.5735 = 16.91 fl oz. To go the other way, multiply fl oz by 29.5735.

One cubic centimetre (cm\u00b3) equals exactly one millilitre (mL). They are completely interchangeable units of volume.

There are 8 US pints in a US gallon, and 8 UK pints in a UK imperial gallon. Note that a US pint (473 mL) is smaller than a UK pint (568 mL).

One cubic metre (m\u00b3) equals exactly 1,000 litres. A cubic metre is the SI base unit for volume, while the litre is the more practical everyday unit used in cooking, beverages, and fuel.
