How to convert cups to grams, and grams to cups

For the most common ingredients, the conversion tables below give approximate gram equivalents for various US cup volumes (from 1 tablespoon up to 1 cup). These cover everyday baking ingredients such as flour, cocoa, butter and sugars. Use the tables to convert 1 US cup of a given ingredient into grams, or to estimate how many cups a given gram quantity represents. Bear in mind these are approximate values because different brands and packing methods can change the weight.

How to measure ingredients accurately

Weighing ingredients is far more accurate than measuring by volume. Cup measurements can vary each time you scoop, whereas weight stays constant. If you want predictable, repeatable baking and cooking results, use grams on a digital kitchen scale rather than cups.

If you must use cups, spoon ingredients into the cup and level with a knife instead of scooping and packing, which can significantly alter the volume.

Helpful tips

  • Different ingredients pack into cups differently. For consistent results, use weight rather than volume wherever possible.
  • Volume measurements can be more useful for certain recipes, such as cooking rice or couscous, where liquid ratios matter more than precise weight.
  • Spoon and level dry ingredients for the most accurate cup measurement rather than scooping directly with the cup.
  • Not all sugars or flours are interchangeable by volume — caster sugar, demerara and muscovado will differ in both weight and texture. Check the notes for each ingredient when in doubt.
  • Use a reliable digital kitchen scale for the best accuracy.

FAQs

What’s the difference between cups and grams?

Cups measure volume, while grams measure weight. US recipes commonly use cups (a volume measure), whereas the UK and other countries typically use grams (metric weight). Because they measure different things, the gram value for one cup depends entirely on the ingredient being measured.

How much is 1 cup in grams?

There is no single answer because 1 cup can weigh differently depending on the ingredient. For example, 1 cup of butter will weigh far more in grams than 1 cup of marshmallows. Use ingredient-specific conversion tables to find the correct gram equivalent.

What is a cup measurement in the UK?

A US cup is typically 240ml, while a UK cup is commonly regarded as 250ml. The difference is small and usually won’t affect most home recipes, but for multiple batches or commercial baking it can make a noticeable difference.
