Formula and Step-by-Step

cups × 127g/cup ÷ 453.592g/lb = pounds
  1. Start with 39.79 cups of bread flour
  2. 1 cup of bread flour = 127g
  3. 39.79 × 127 = 5,053.33g
  4. Convert grams to pounds: 5,053.33 ÷ 453.592 = 11.14 lb

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

Measuring Tip

For the most consistent results, weigh bread flour on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is a Pound?

The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.

Frequently Asked Questions

About 11.14 lb, 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), then divide by 453.592 to convert grams to pounds. For 39.79 cups: 39.79 × 127 = 5,053.33g, then 5,053.33 ÷ 453.592 = 11.14 lb.
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: 11.14 lb × 453.592 = 5,053.33g, then 5,053.33g ÷ 127 = 39.79 cups. Or use the Pounds to Cups converter.
