A US tablespoon is 14.79 mL, usually rounded to 15. A metric tablespoon is exactly 15 mL and an Australian tablespoon is 20 mL, which is a third more than either.

How to use Tablespoons to ML Converter

  1. Enter the tablespoons. Fractions such as 1.5 are fine.
  2. Check which definition. All three are shown, since a recipe rarely says which it means.

About converting tablespoons to millilitres

The tablespoon is a cooking measure with at least three definitions in current use, and unlike most unit confusion this one is not historical — all three are live today. The United States customary tablespoon is 14.79 millilitres, defined as half a US fluid ounce. The metric tablespoon adopted across most of Europe, Canada and New Zealand is exactly 15 millilitres, chosen for tidiness. Australia is the outlier at 20 millilitres, a third larger than either. For anything measured in bulk the difference between 14.79 and 15 is irrelevant, which is why the two are used interchangeably without much harm. The Australian tablespoon is a real problem. Following an Australian recipe with a 15 millilitre spoon under-measures by twenty-five percent, and following an American recipe with a 20 millilitre spoon over-measures by a third. For oil or stock that is survivable; for baking powder, bicarbonate of soda, salt or yeast it is not, because those are the ingredients measured in single spoons and the ones where proportion decides the outcome. The teaspoon relationship differs too. Three teaspoons make a tablespoon everywhere except Australia, where the 5 millilitre teaspoon means four fit into the larger tablespoon. Worth knowing before halving a recipe. The larger source of error in practice is neither of these: a heaped spoon of a dry ingredient can hold half again as much as a level one, which swamps every national difference discussed here.

Frequently asked questions

How many ml is a tablespoon?
14.79 mL in the United States, 15 mL in most metric countries, and 20 mL in Australia. The US and metric figures are close enough to be interchangeable in cooking; the Australian one is not, and using it by mistake adds a third to every measure.
How many teaspoons in a tablespoon?
Three, in the US, UK and metric systems. Australia is the exception again — its tablespoon is 20 mL against a 5 mL teaspoon, so four teaspoons make one Australian tablespoon.
Does the difference actually matter?
For oil, stock or water, rarely. For baking powder, salt, yeast or spices it matters a great deal — those are measured in single spoons and a third more leavening or salt is the difference between a good result and an inedible one.
Should I measure level or heaped?
Level, unless the recipe says otherwise. A heaped tablespoon of a dry ingredient can hold half again as much as a level one, which is a larger error than any of the national differences discussed here.
