How Much Is 0.42 Cups of Self-Rising Flour in Ounces?
0.42 cups of self-rising flour weighs 1.78 oz. This is based on self-rising flour having a density of 120g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 0.42 cups.
Formula and Step-by-Step
- Start with 0.42 cups of self-rising flour
- 1 cup of self-rising flour = 120g
- 0.42 × 120 = 50.4g
- Convert grams to ounces: 50.4 ÷ 28.3495 = 1.78 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects self-rising flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.
