Milliliters to Cups Converter

What this does

So you have an amount in millilitres, maybe off a carton or a metric jug, and your recipe speaks in cups. This converter turns millilitres into cups in a second. The only thing to set is which cup you mean, since cups come in a couple of sizes, and the tool lets you pick before it does the sum.

How to use it

1. Enter the amount, and choose millilitres or litres.
2. Pick your cup size, US Legal (240 ml) or Imperial (284 ml).
3. Press Calculate.

No ingredient needed here, because both millilitres and cups measure volume.

How the conversion works

It is just your millilitres divided by the size of one cup:

cups = millilitres ÷ cup size in ml

With the US Legal cup at 240 ml, 240 millilitres is exactly 1 cup, and 500 millilitres is about 2.08 cups. Litres are turned into millilitres first, so 1 litre is 1000 millilitres, or just over 4 cups.

Which cup do you mean?

A cup is not one fixed size, so the tool offers two. The US Legal cup is 240 millilitres, the official cup on United States nutrition labels. The Imperial cup is 284 millilitres, the older British cup from vintage UK recipes.

Two more are out there: the US customary cup of about 237 millilitres, used in most American recipes, and the metric cup of 250 millilitres, used across the UK, Australia, and Canada. They are close but not identical, so match the cup to wherever your recipe came from.
