Frequently Asked Questions

How many Cups are in a Milliliter?

One milliliter is equivalent to 0.00422675 US customary cups. Because the milliliter is a very small unit, you will always end up with a small decimal unless you are converting hundreds of milliliters. For most practical kitchen uses, 237 ml is treated as 1 cup.

Is a Cup the same size in every country?

No, and this is a common source of baking errors! A US Customary cup is ~237 ml, but a Metric cup (used in the UK, Australia, and Canada) is exactly 250 ml. If you are using a European recipe, it is safer to measure in milliliters to ensure the ratios stay correct.

How do I convert ML to Cups easily?

If you don’t have a calculator, divide your milliliters by 240. For example, if you have 480 ml of water, 480 divided by 240 is exactly 2 cups. This “240 rule” is the standard used for US food labeling and works perfectly for nearly all household cooking needs.
