Formula and Step-by-Step

cups × 127g/cup = grams
  1. Start with 3 cups of bread flour
  2. 1 cup of bread flour = 127g
  3. 3 × 127 = 381g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 381.00 g, based on bread flour having a density of 127g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 127 (grams per cup for bread flour). For 3 cups: 3 × 127 = 381.00 g.
For the most accurate results, weigh bread flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring cup and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 127 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 139.7 to 158.75 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 381.00 g ÷ 127 = 3 cups. Or use the Grams to Cups converter.
