How Much Is 40 Grams of Onions (Diced) in Cups?
Converting 40 grams of onions (diced) to cups gives 0.25 cups. Divide by the density of onions (diced) (160g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 40 grams of onions (diced)
- 1 cup of onions (diced) = 160g
- 40g ÷ 160g/cup = 0.25 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
The weight of diced produce per cup depends on how finely it is cut. Smaller dice packs more tightly and weighs more per cup than large chunks.

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?
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.
