How it works
Both units measure volume, so they are always in the same ratio: one tablespoon (US) equals 14.786765 millilitres. The calculator multiplies the number of tablespoons (US) you type by 14.786765 to give millilitres, and when you type into the millilitres field it divides by the same factor to give tablespoons (US). Because the ratio never changes, doubling the tablespoons (US) always doubles the millilitres. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).
How to convert tablespoons (US) to millilitres
- Write down the value in tablespoons (US), for example 1 tbsp.
- Multiply by the conversion factor 14.786765 (because 1 tablespoon (US) = 14.786765 mL).
- 1 × 14.786765 = 14.786765 mL.
- To go back from millilitres to tablespoons (US), divide by 14.786765 – or multiply by 0.067628045.
