Cups to Grams Converter
Convert between cups and grams using this calculator tool. Note that because the cup is a unit of volume and gram is a unit of weight, you will need to choose an ingredient from the drop-down list or enter a density figure. If you're unsure which cup option to choose, see the explanation here.

Converting Between Cups And Grams
Due to the fact that the cup is a unit of volume and the gram is a unit of weight, converting between the two requires a substance density figure to be included. To give a crude example, a cup full of flour will weigh less than a cup full of water.
Please be aware that the list of ingredient options included in the converter (and below) are approximations, meaning the result you receive will be an estimate. The ingredient densities were sourced from the Food and Agricultural Organisation of the United Nations as well as other information sources. A full list of these is available on the baking ingredient conversions page.

Which Cup Should I Use?
As you'll have noticed from the list of conversion options in the converter tool, there are multiple options for the humble cup. If you need some clarification as to which cup is used in your recipe, see our article how many grams are in a cup?
- The US Cup (Customary) - referenced in recipes in the US. Measures 236.588 mL.
- The Metric Cup - used (occasionally) in the UK as well as Australia, New Zealand, Canada and the rest of the Commonwealth. It measures 250mL. In the UK, cups have rarely been used in recipes since the 1970s.
- The Imperial Cup - you may find the UK imperial cup referenced in pre-1970 recipes. The imperial cup measures 284.131 mL.
