Formula and Step-by-Step

cups × 160g/cup = grams
  1. Start with 1.5 cups of onions (diced)
  2. 1 cup of onions (diced) = 160g
  3. 1.5 × 160 = 240g

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 240.00 g, 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.
Multiply the number of cups by 160 (grams per cup for onions (diced)). For 1.5 cups: 1.5 × 160 = 240.00 g.
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: 240.00 g ÷ 160 = 1.5 cups. Or use the Grams to Cups converter.
