Formula and Step-by-Step

cups × 245g/cup ÷ 453.592g/lb = pounds
  1. Start with 1 cup of tomato sauce
  2. 1 cup of tomato sauce = 245g
  3. 1 × 245 = 245g
  4. Convert grams to pounds: 245 ÷ 453.592 = 0.54 lb

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

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

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.
