How Much Is 2.21 Ounces of All-Purpose Flour in Cups?
Converting 2.21 ounces of all-purpose flour to cups gives 0.50 cups. First convert to grams (2.21 oz = 62.65g), then divide by the density of all-purpose flour (125.16g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 2.21 ounces of all-purpose flour
- Convert ounces to grams: 2.21 × 28.35 = 62.65g
- 1 cup of all-purpose flour = 125.16g
- 62.65g ÷ 125.16g/cup = 0.50 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects all-purpose flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.
