Formula and Step-by-Step

cups × 160g/cup = grams
  1. Start with 0.5 cups of onions (diced)
  2. 1 cup of onions (diced) = 160g
  3. 0.5 × 160 = 80g

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

Mental Math Shortcut

Half measures: take the weight of 1 cup (160g) and divide by 2.

Measuring Tip

Raw and cooked produce have very different weights per cup. Cooked vegetables shrink and become denser. These conversions are for raw produce.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 80.00 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 0.5 cups: 0.5 × 160 = 80.00 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: 80.00 g ÷ 160 = 0.5 cups. Or use the Grams to Cups converter.
