Formula and Step-by-Step
- Start with 17.66 ounces of all-purpose flour
- Convert ounces to grams: 17.66 × 28.35 = 500.65g
- 1 cup of all-purpose flour = 125.16g
- 500.65g ÷ 125.16g/cup = 4.00 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
