Formula
mL = cups x cup size (236.588 or 250) | Cups = mL / cup size

Frequently asked questions

Which cup size should I use?

US recipes (including most recipe blogs and cookbooks) use the 236.588 mL US cup. Australian, New Zealand and many UK recipes use the simpler 250 mL metric cup. When in doubt, check the recipe's country of origin.

Does the cup-size difference actually matter for baking?

For most recipes, the ~5-6% difference between US and metric cups is small enough not to ruin a dish, but it can matter for precise baking (bread, pastry). When precision counts, weighing ingredients in grams avoids the ambiguity entirely.
