How Much Is 1.09 Cups of All-Purpose Flour in Pounds?
1.09 cups of all-purpose flour weighs 0.30 lb. This is based on all-purpose flour having a density of 125.16g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.09 cups.
Formula and Step-by-Step
- Start with 1.09 cups of all-purpose flour
- 1 cup of all-purpose flour = 125.16g
- 1.09 × 125.16 = 136.42g
- Convert grams to pounds: 136.42 ÷ 453.592 = 0.30 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
