What This Calculator Does
The Cups to Milliliters Converter translates US cups into metric milliliters, which is how most of the world measures liquid ingredients. American recipes use cups while European and Asian recipes use milliliters, so this conversion is essential when following international cookbooks or scaling recipes.
How It Works
One US cup equals approximately 236.588 milliliters. Multiply the number of cups by this factor. A metric cup (used in Australia and the UK) is 250 ml, slightly larger.
Example
1 cup of water is 236.59 ml. A recipe calling for 2 cups of milk needs 473.18 ml. A half cup of sugar is 118.29 ml.
Formula
ml = cups x 236.5881 US cup = 236.588 ml.
