Metric Cup to Milliliter Converter

About this calculator

The metric cup, used in Australia, New Zealand, the UK, and many international recipes, is defined as exactly 250 milliliters — a clean, round figure chosen specifically to make metric kitchen measurement simple, unlike the US customary cup, which equals about 236.588 mL. Because the two systems are close but not identical, a recipe written for one can quietly throw off ratios of liquid to dry ingredients if you assume they're interchangeable.

This calculator converts any number of metric cups into milliliters (and liters for larger volumes), so home cooks and bakers following recipes from a different measurement tradition can convert accurately rather than approximating. Home cooks adapting international recipes, bakers scaling batches, and recipe writers and food bloggers preparing metric versions of their instructions rely on it to keep proportions exact.
