How to use the volume converter
- 1 Type the value you want to convert.
- 2 Choose the unit to convert from and the unit to convert to.
- 3 Press ⇄ to swap the two units.
- 4 Read the result, and see the same volume in every other unit in the table below.
Kitchen and tank volumes
Check whether a recipe is American, British or metric before converting cups and pints: a US cup is 237 ml, a metric cup 250 ml. For litres and gallons alone, use Liters to Gallons and choose US or UK gallons.
- Measure liquids in a jug at eye level for accuracy.
- For dry ingredients, weigh them instead; see Ounces to Grams.
- Tank capacity in cubic metres times 1,000 gives litres.
Features
US and UK units
Separate US and UK pints and gallons, because they differ by about 20%.
Kitchen units
US teaspoons, tablespoons, cups and fluid ounces for recipes.
Space and tanks
Cubic metres and cubic feet for rooms, freezers, tanks and shipping.
When to use it
Following recipes
Convert US cups and tablespoons to millilitres. One US cup is 236.6 ml, so two cups is about 473 ml. For flour and sugar by weight, see Ounces to Grams.
Fuel and tanks
Water tanks, fuel tanks and pools are measured in litres, gallons or cubic metres. For simple litre and gallon conversion use Liters to Gallons.
Storage and shipping
Fridges, freezers and car boots are rated in litres or cubic feet. A 300 litre fridge is 10.6 cubic feet.
Medicine and drinks
Medicine doses are in millilitres. A teaspoon is about 5 ml, but always use the measuring cup or syringe supplied.

Frequently asked questions
How many millilitres are in a cup?
A US cup is 236.59 ml. A metric cup used in Australia and some other countries is 250 ml, and a UK cup in older recipes is about 284 ml.
How many litres in a US gallon?
3.785 litres. A UK gallon is 4.546 litres.
How many tablespoons in a cup?
16 US tablespoons make one US cup, and 3 teaspoons make a tablespoon.
How many ml is a fluid ounce?
A US fluid ounce is 29.57 ml and a UK fluid ounce is 28.41 ml.
How many litres are in a cubic metre?
1,000 litres. A cubic metre of water weighs about one tonne.
How do I convert cubic feet to litres?
Multiply by 28.3168. A 10 cubic foot freezer holds 283 litres.
Is a pint the same in the US and UK?
No. A US pint is 473 ml and a UK pint is 568 ml, which is why a pint of beer in the UK is larger.
Can I convert volume to weight here?
No, because weight depends on what the liquid or powder is. Water is about 1 gram per millilitre, but oil, flour and sugar are different.
What is a cubic centimetre?
The same as a millilitre. Engine sizes in cc, such as 1300 cc, are volumes in cubic centimetres, or 1.3 litres.
Which units should I use for baking?
Weight in grams is the most reliable. If a recipe uses cups, check whether it is American, as US and metric cups differ.
Why are there two kinds of gallon and pint?
The United States kept older English measures, while Britain redefined its units in 1824. The British pint and gallon are therefore about a fifth larger than the American ones with the same names.
How do I measure the volume of a tank?
For a rectangular tank, multiply length, width and height in metres to get cubic metres, then multiply by one thousand for litres. For a round tank, multiply the area of the circle by the height.
