How Much Is 0.21 Cups of Water in Grams?
0.21 cups of water weighs 49.68 g. This is based on water having a density of 236.59g 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 0.21 cups.
Formula and Step-by-Step
- Start with 0.21 cups of water
- 1 cup of water = 236.59g
- 0.21 × 236.59 = 49.68g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Water at Different Amounts

For reference, 0.21 cups of water (49.68g) is close in weight to a large egg (no shell) (50g).

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?
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.
