How this calculator works
This page uses the US customary tablespoon, exactly 1/256 of a US gallon. The exact gallon of 231 cubic inches gives 14.78676478125 mL per tablespoon. A metric tablespoon is 15 mL, so a recipe using metric spoons needs that separate convention.
Formula
US tbsp = mL / 14.78676478125; mL = US tbsp x 14.78676478125. For a 15 mL metric spoon, divide mL by 15.
Worked example
A 30 mL quantity is about 2.028841362 US tbsp, but exactly 2 metric tablespoons of 15 mL each. Half a US tablespoon is 7.393382390625 mL.
