ml to Cups Conversion: The Complete Guide
1 US cup = 237 ml. That's the core conversion. But this guide covers every volume you'll encounter in a recipe — from a teaspoon to a full quart — so you'll never need to search again.
You're following a European or Australian recipe and it says "250ml" but your measuring cups only show fractions of a cup. Conversion time. Or maybe you're going the other direction—metric measuring cups for a US recipe. Either way, this guide has you covered.

US Cup vs. Metric Cup: Does It Matter?
The US cup (237 ml) and the metric cup (250 ml) are 13 ml apart — about 5.5%. For a single cup, you'll never notice the difference. But it adds up: if you're making a large batch that calls for 8 cups of liquid, you're off by about 104 ml (nearly half a cup) if you use metric cups for a US recipe. That can actually matter.
For precision baking, use the measuring system that matches your recipe's country of origin, or just convert using the exact ml values from the table above.
Practical Volume Landmarks to Memorize
Instead of looking up every value, just memorize these four anchor points and derive everything else from them:
1 teaspoon = 5 ml
1 tablespoon = 15 ml (3 teaspoons)
1 cup = 237 ml (16 tablespoons)
1 liter ≈ 4.2 cups (1000 ml)
Once those are locked in, you can build any conversion by multiplication. Half a liter = half of 4.2 cups = 2.1 cups ≈ 2 cups + 1.5 tablespoons. Good enough for any savory recipe, and honestly for most baking too.
ml Markings on Measuring Cups
Most US liquid measuring cups—the clear pitchers with a pour spout—have both cup fractions and ml markings on the side. If yours does, just use the ml line directly when your recipe calls for ml. No conversion needed. If you only have dry measuring cups (the nesting kind), you'll need to calculate: fill to the brim of the right cup size and match it to the ml equivalent in the table above.
Converting Recipes from Metric
European and Australian baking recipes typically use ml for liquids. The simplest solution? Don't convert at all—just buy a liquid measuring cup that shows ml markings up to 500 ml or 1 liter. They cost a few dollars and eliminate every conversion error. But if you need to cook right now, the table above has you covered.
Frequently Asked Questions
How many ml is 1 cup?
1 US cup equals 236.6 ml, usually rounded to 237 ml or 240 ml for everyday use. The US legal cup (used in nutrition labeling) is exactly 240 ml.
How many ml is half a cup?

Is 250 ml equal to 1 cup?
250 ml is the metric cup, used in Australia, Canada, and New Zealand. It's a bit larger than the US cup (237 ml). For most recipes the 13 ml gap is negligible, but it adds up with larger quantities.
How do I convert ml to cups without a calculator?
Divide the ml amount by 237 (for US cups) or by 250 (for metric cups). For quick mental math: 120 ml ≈ ½ cup, 180 ml ≈ ¾ cup, 240 ml ≈ 1 cup, 480 ml ≈ 2 cups, 960 ml ≈ 4 cups.
