Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 160g/cup = cups
  1. Start with 1.5 pounds of onions (diced)
  2. Convert pounds to grams: 1.5 × 453.59 = 680.39g
  3. 1 cup of onions (diced) = 160g
  4. 680.39g ÷ 160g/cup = 4.25 cups

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

Measuring Tip

For consistent results, weigh onions (diced) rather than measuring by volume. A cup of diced produce can vary by 20% depending on dice size.

Frequently Asked Questions

About 4.25 cups, based on onions (diced) having a density of 160g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert pounds to grams (1 pound = 453.592g), then divide by 160 (grams per cup). For 1.5 pounds: 1.5 × 453.592 = 680.39g, then 680.39 ÷ 160 = 4.25 cups.
For the most accurate results, weigh onions (diced) on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 4.25 cups × 160g/cup = 680.39g, then 680.39g ÷ 453.592 = 1.5 pounds. Or use the Cups to Pounds converter.
