Formula and Step-by-Step

fluid ounces × 30.63g/fl oz ÷ 28.3495g/oz = ounces
  1. Start with 13.07 fluid ounces of buttermilk
  2. 1 fluid ounce of buttermilk = 30.63g
  3. 13.07 × 30.63 = 400.27g
  4. Convert grams to ounces: 400.27 ÷ 28.3495 = 14.12 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.
