Formula and Step-by-Step
- Start with 1.5 quarts of buttermilk
- 1 quart of buttermilk = 980g
- 1.5 × 980 = 1,470g
- Convert grams to ounces: 1,470 ÷ 28.3495 = 51.85 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.
