Formula
grams = cups x grams per cup for that ingredient (1 US cup = 236.5882365 mL exactly)Understanding Cooking Conversion
A cup measures volume while a gram measures mass, so the conversion depends on how heavy the ingredient is for its volume. A cup of all-purpose flour weighs about 120 grams, a cup of granulated sugar about 198 grams, and a cup of water about 236 grams. This tool uses published ingredient weight charts from a professional baking source and a US customary cup of exactly 236.5882365 mL. Weighing is more accurate than scooping because flour can vary by 20 percent depending on how it is packed.
Tips and Best Practices
- 1Spoon flour into the cup and level it; scooping straight from the bag packs in up to 20 percent more.
- 2For recipes from outside the US, check whether "cup" means 250 mL (metric cup) instead of 236.6 mL.
- 3A kitchen scale removes nearly all of the guesswork when baking.
Real-World Example
2 cups of all-purpose flour is about 2 x 120 = 240 grams. 1 cup of butter (two sticks) is about 226 grams.
Common Mistakes to Avoid
- Assuming a cup of every ingredient weighs the same.
- Mixing fluid ounces (volume) with ounces (weight).
- Using the flour figure for whole wheat or cake flour, which weigh differently.
How to Use
- Pick the unit you have in the left selector and the unit you want in the right selector.
