From the recipe to your kitchen

For cups to millilitres, choose cups as From and millilitres as To. No ingredient is needed for this volume conversion. To convert cups to grams, choose the ingredient as well. The result updates as you type.

This tool uses the ingredient-density estimates and household measurement definitions from the CookBook app. No account is needed.

Which cup does your recipe mean?

A US customary cup is about 237 ml. A metric or Australian cup is 250 ml, while an imperial cup is about 284 ml. Australian tablespoons are 20 ml; metric tablespoons are 15 ml.

Choose the recipe’s convention, rather than the language you speak. Fluid ounces measure volume; ounces measure weight. They need different conversions.

Compare flour weights for US and 250 ml cups

A cup of flour is not a cup of honey

Volume-to-weight results use the ingredient-density table from the CookBook app: volume in millilitres multiplied by the selected ingredient’s estimated grams per millilitre. Variety, moisture and packing affect the result. Use the recipe’s stated gram weights when available.

Frequently asked questions

How many millilitres are in 1 cup?

A US customary cup is about 237 ml. A metric or Australian cup is 250 ml, and an imperial cup is about 284 ml. Choose the system used by your recipe before converting; the page language does not decide the cup size.

How do I convert cups to grams?

Can I convert grams back to cups?

Yes. Use Swap units or select grams as the starting unit and cups as the result. Keep the ingredient and the cup system the same for the reverse conversion.

Are US and Australian tablespoons the same?

No. This calculator uses about 15 ml for a US tablespoon and 20 ml for an Australian tablespoon. Choose the recipe measurement system before converting.
