Volume conversions: cups, ml, dl and spoons

Volume conversions are the safe ones: a millilitre is a millilitre regardless of what is in the jug, so converting between cups, decilitres, millilitres, tablespoons and teaspoons is exact arithmetic rather than an estimate.

The catch is that a "cup" is not one thing. This page uses the US customary cup of 240 ml. A metric cup is 250 ml β€” about 4% larger β€” and an Australian tablespoon is 20 ml where everyone else uses 15 ml. For liquids that difference is usually harmless; for raising agents in baking it is not.

A cup is not one size

The tables above use the US customary cup of 240 ml, which is what American recipes and this site mean by "a cup". A metric cup is 250 ml, used in Australia, New Zealand and parts of Scandinavia β€” about 4% larger. An old imperial UK cup was 284 ml, though modern British recipes almost always give weights instead.

For liquids, 4% rarely matters. For baking powder, salt or yeast it can, which is why those are worth measuring by spoon or scale rather than by cup.

Spoons are not standard either

A tablespoon is 15 ml almost everywhere β€” except Australia, where it is 20 ml, or four teaspoons rather than three. If you are following an Australian recipe with a European spoon, add a teaspoon to every tablespoon.

Fluid ounces are a volume

A fluid ounce measures space, an ounce measures mass, and they are only interchangeable for water. A US fluid ounce is 29.57 ml; a UK fluid ounce is 28.41 ml. When an American recipe says "8 oz of milk" it means fluid ounces β€” a cup.
