How Much Is 12.66 Ounces of Self-Rising Flour in Cups?
12.66 ounces of self-rising flour equals 2.99 cups. Self-rising flour has a density of 120g 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 12.66 ounces of self-rising flour
- Convert ounces to grams: 12.66 × 28.35 = 358.90g
- 1 cup of self-rising flour = 120g
- 358.90g ÷ 120g/cup = 2.99 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For the most consistent results, weigh self-rising flour on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.
