What this converter does

A US cup is a standard kitchen measurement defined as exactly 236.588 milliliters. This converter applies that exact relationship in either direction, so switching between a metric-marked container and a recipe written in cups takes one lookup.

Why “cup” isn’t the same size everywhere

This tool uses the US customary cup (236.588 mL). Other countries define “cup” slightly differently, a metric cup, used in Australian and UK recipes, is exactly 250 mL, noticeably larger than the US cup. If you’re following a recipe from a metric-cup country, using this US-cup conversion would introduce a small but real error, worth checking which cup definition your specific recipe source is using before converting.
