Tool guide
What is this Converter?
The Cups to mL Converter is a specialized culinary tool designed to translate recipe measurements from cups into milliliters. It supports different global standards like the Metric Cup (250 mL), US Customary Cup (236.59 mL), and US Legal Cup (240 mL).
Why use this tool?
Baking and cooking require precision, and using the wrong cup size can throw off a recipe. This tool lets you specify exactly which cup standard you are using so you can measure liquids and dry ingredients accurately in milliliters.
US Cups vs Metric Cups
This trips up a lot of American home cooks following international recipes. A US customary cup is about 236.6 mL, and the US legal cup used on nutrition labels is 240 mL. A metric cup, common in Australian and European recipes, is 250 mL. That 10 to 14 mL gap per cup adds up fast in baking, where ratios matter, so it helps to know which standard a recipe was written for before you convert.
A quick rule of thumb for US kitchens: 1 cup is roughly 237 mL, half a cup is about 118 mL, and a quarter cup is close to 59 mL. When a recipe does not say, assume US customary cups for American sources and metric cups for most international ones.
Common Cup to mL Conversions
These US customary cup values cover the amounts most recipes call for:
- 1/4 cup is about 59 mL
- 1/3 cup is about 79 mL
- 1/2 cup is about 118 mL
- 2/3 cup is about 158 mL
- 3/4 cup is about 177 mL
- 1 cup is about 237 mL
For dry ingredients like flour or sugar, weighing on a kitchen scale is even more reliable than volume, since a cup can be packed loosely or tightly. Use this converter for liquids and as a fast reference when a scale is not handy.
