ABOUT THIS CONVERSION
Convert US tablespoons to milliliters
This page converts US tablespoons (tbsp) to milliliters (mL). Convertor4U first interprets the input using US tablespoon's definition, then expresses the same quantity in Milliliter. The result is calculated from the stored factor and offset definitions, not from a rounded lookup table.
Real-world example
For adapting a recipe written with a different measuring system, an input of 1 tbsp converts to 14.78676478 mL. Keep extra digits while calculating, then round only the final value to the precision the task actually needs.
Rounding and precision
Round to a measure you can reproduce: a sensible fraction of a spoon, a whole milliliter, or the resolution of a kitchen scale. For very small quantities, avoid converting to an impractically tiny cup fraction.
Regional context
A US cup is about 236.588 mL; a metric cup is 250 mL. Australian tablespoon conventions can differ from the US value, and Imperial fluid measures differ from US measures. Always identify the recipe's origin.
Common mistake
Volume conversion cannot determine ingredient mass without the ingredient's density.
Editorial method
Definitions and sources are listed below. Calculations retain more precision than the default display and round only for presentation.
