Formula and Step-by-Step

cups × 102g/cup ÷ 453.592g/lb = pounds
  1. Start with 17.79 cups of rye flour
  2. 1 cup of rye flour = 102g
  3. 17.79 × 102 = 1,814.58g
  4. Convert grams to pounds: 1,814.58 ÷ 453.592 = 4.00 lb

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

Measuring Tip

Humidity affects rye flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Frequently Asked Questions

About 4.00 lb, based on rye flour having a density of 102g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 102 (grams per cup for rye flour), then divide by 453.592 to convert grams to pounds. For 17.79 cups: 17.79 × 102 = 1,814.58g, then 1,814.58 ÷ 453.592 = 4.00 lb.
For the most accurate results, weigh rye 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 102 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 112.2 to 127.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 4.00 lb × 453.592 = 1,814.58g, then 1,814.58g ÷ 102 = 17.79 cups. Or use the Pounds to Cups converter.
