Formula and Step-by-Step

cups × 245g/cup ÷ 453.592g/lb = pounds
  1. Start with 2.78 cups of tomato sauce
  2. 1 cup of tomato sauce = 245g
  3. 2.78 × 245 = 681.1g
  4. Convert grams to pounds: 681.1 ÷ 453.592 = 1.50 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.

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
