How Much Is 140 Ounces of All-Purpose Flour in Cups?
140 ounces of all-purpose flour equals 31.71 cups. All-purpose flour has a density of 125.16g per cup. A lighter ingredient like cocoa powder (86g/cup) would fill even more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 140 ounces of all-purpose flour
- Convert ounces to grams: 140 × 28.35 = 3,968.93g
- 1 cup of all-purpose flour = 125.16g
- 3,968.93g ÷ 125.16g/cup = 31.71 cups
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.
