Formula and Step-by-Step

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

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

Mental Math Shortcut

For 1 cup of onions (diced), just remember: 160g. Double it for 2 cups (320g), halve it for a half cup (80g).

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?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 160.00 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 cup: 1 × 160 = 160.00 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: 160.00 g ÷ 160 = 1 cup. Or use the Grams to Cups converter.
