Formula and Step-by-Step

cups × 245g/cup ÷ 453.592g/lb = pounds
  1. Start with 990 cups of buttermilk
  2. 1 cup of buttermilk = 245g
  3. 990 × 245 = 242,550g
  4. Convert grams to pounds: 242,550 ÷ 453.592 = 534.73 lb

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.
