functions Conversion Formula
Cups = Grams ÷ Grams per Cup
For example, if you have 30 grams of all-purpose flour
(120 g/cup):
30 ÷ 120 = 0.25 cups
Each ingredient has a different grams-per-cup value because ingredients have different densities — which is exactly why this tool exists.

Why 30 Grams Gives Different Cup Amounts
When you convert 30 grams to cups, you will get a different answer for every ingredient you measure. This is because the cup is a unit of volume, not weight. Two ingredients can fill the same cup yet weigh completely different amounts — a cup of feather-light icing sugar and a cup of dense honey are both "one cup," but they weigh 130g and 340g respectively.
This is why professional bakers prefer weighing ingredients in grams. 30 grams is always 30 grams, regardless of how it is spooned, scooped, or packed. When you use grams, you eliminate the variability introduced by different measuring techniques — leading to more consistent and reliable baked goods every time.
If a recipe lists 30 grams of an ingredient, use the table above or the calculator to find the correct cup amount. Remember to choose the right ingredient from the dropdown, because even similar ingredients (e.g., all-purpose flour vs. bread flour) can have slightly different densities.
