Conversion Formulas

Convert grams to cups and cups to grams using our conversion chart, and conversion calculator, and learn the relationship between these two units.

Conversion of grams to cups and cups to grams is easy, but one must be aware that the gram is a unit of mass, while the cup is a unit of volume and some assumptions must be made. Also, there are two "standard" size cups, the US cup and the Imperial cup.

Gram is a metric system unit of mass and it was first defined as a mass of 1 milliliter (1 cm3) of water at 0°C (later at 4°C) - modern definition of a gram and a kilogram is based on the fixed numerical value of the Planck constant h, but the actual difference is very small and can be ignored in everyday situations.

Thus, cups-grams conversion formulas are:

1 US Cup = 240ml = 240 grams (of water)

1 Imp Cup = 284.131ml = 284.131 grams (of water)

It must be emphasized that if You have a liquid that is less dense than the water (oil, gas/petrol, etc.) or denser than the water (salty water, for example) then in order to accurately convert the grams to cups and cups to grams, You also have to take the density of the liquid into account.


 

Grams to Cups and Cups to Grams Conversion Examples

If You have 2 cups (US/Imp) of water that would be:

V(g) = 240 * V(US Cup) = 240 * 2 = 480 ml = 480 grams (of water)

V(g) = 284.131 * V(Imp Cup) = 284.131 * 2 = 568.262 ml = 568.262 grams (of water)

Similarly, if You have 100g of water, that would be:

100g = (100g / 240) = 0.41666 US Cups

100g = (100g / 284.131) = 0.3519 Imp Cups

etc.
