Formula and Step-by-Step

fluid ounces × 30.63g/fl oz ÷ 28.3495g/oz = ounces
  1. Start with 12 fluid ounces of buttermilk
  2. 1 fluid ounce of buttermilk = 30.63g
  3. 12 × 30.63 = 367.5g
  4. Convert grams to ounces: 367.5 ÷ 28.3495 = 12.96 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.

Frequently Asked Questions

About 12.96 oz, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
