How Much Is 21 Cups of Cornmeal in Grams?
21 cups of cornmeal weighs 3,150.00 g. This is based on cornmeal having a density of 150g 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 21 cups.
Formula and Step-by-Step
- Start with 21 cups of cornmeal
- 1 cup of cornmeal = 150g
- 21 × 150 = 3,150g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Cornmeal weigh 150g per cup when dry. Cooked weight per cup will be different.

Understanding the Units
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
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.
