Good to know before cooking.
Can I enter 1 1/2 cups?
Yes. Whole numbers, decimals, simple fractions, and mixed fractions all work.
Does the tool convert cups to grams?
No. Scaling and unit conversion are different jobs because grams depend on the ingredient. Use the separate Cooking Converter when you need weight conversions.
