How Much Is 1.3 Cups of Buttermilk in Ounces?
1.3 cups of buttermilk weighs 11.23 oz. This is based on buttermilk having a density of 245g 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 1.3 cups.
Formula and Step-by-Step
- Start with 1.3 cups of buttermilk
- 1 cup of buttermilk = 245g
- 1.3 × 245 = 318.5g
- Convert grams to ounces: 318.5 ÷ 28.3495 = 11.23 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
