Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 236.59g/cup = cups

Start with 1.5 pounds of water
Convert pounds to grams: 1.5 × 453.59 = 680.39g
1 cup of water = 236.59g
680.39g ÷ 236.59g/cup = 2.88 cups

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.
