How Much Is 3 Cups of Onions (Diced) in Grams?
3 cups of onions (diced) weighs 480.00 g. This is based on onions (diced) having a density of 160g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 cups.
Formula and Step-by-Step
- Start with 3 cups of onions (diced)
- 1 cup of onions (diced) = 160g
- 3 × 160 = 480g
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 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?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
