Formula and Step-by-Step

quarts × 976g/qt ÷ 28.3495g/oz = ounces
  1. Start with 4.2 quarts of milk
  2. 1 quart of milk = 976g
  3. 4.2 × 976 = 4,099.2g
  4. Convert grams to ounces: 4,099.2 ÷ 28.3495 = 144.60 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.
