Formula and Step-by-Step

grams ÷ 160g/cup = cups
  1. Start with 30 grams of onions (diced)
  2. 1 cup of onions (diced) = 160g
  3. 30g ÷ 160g/cup = 0.19 cups

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

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 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.

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 0.19 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.
Divide the grams by 160 (grams per cup) to get cups. For 30 grams: 30 ÷ 160 = 0.19 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: 0.19 cups × 160g/cup = 30g. Or use the Cups to Grams converter.
