Tablespoons to ML Converter
Convert tablespoons to millilitres — and mind the country, because the tablespoon is not the same everywhere. Results update as you type; exact factors shown.
One tablespoon (metric) is 15 millilitres — see the exact factor, not a rounded rule of thumb.
How the tablespoons to ml converter works
Volumes convert through the litre (exactly 1 dm³). The US gallon is exactly 3.785411784 L (231 cubic inches); the imperial gallon is exactly 4.54609 L. A US fluid ounce is 29.5735 mL, an imperial fluid ounce 28.4131 mL; a US pint is 16 US fl oz, an imperial pint 20 imperial fl oz.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.
