How it works

Every unit in this dimension is defined as a ratio to one base unit — the liter. Converting is therefore two multiplications: into the base unit, then out of it.

1 cup = 16 tbsp

US, imperial and metric cups are not the same

A US cup is 236.588 mL, an imperial (UK) cup is 284.131 mL, and a metric cup — used in Australia and most modern recipe books — is exactly 250 mL. A recipe that says "1 cup" can mean any of the three, so this converter lists them separately rather than guessing.

Rounding

Results are rounded to 8 significant figures, adjustable with the slider above. Exact factors are used internally, so chaining conversions does not accumulate error.

Sources

Conversion factors follow NIST Special Publication 811 (Guide for the Use of the International System of Units) and the BIPM SI Brochure, 9th edition. Every factor is checked by an automated round-trip test on each build.
