How to use this tool
Select an amount and both units. Establish whether the recipe uses a US cup or a 250 mL metric cup, and do not treat a volume conversion as a direct conversion to grams.
Results and examples
One US liquid cup is about 236.588 mL. A recipe written for a 250 mL cup therefore uses a different quantity, even though both instructions say one cup.
Limitations
- Ingredient density and packing pressure are not included.
- US customary and imperial volume units should not be mixed.
