Single-conversion pages for water
Working with water
Water sits in the liquids group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. Water is the reference: 1 ml = 1 g. This is the only ingredient where volume and weight convert exactly.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
Frequently asked questions
How many grams are in a cup of water?
One US cup of water weighs about 237 grams (8.36 oz). Water is the reference: 1 ml = 1 g. This is the only ingredient where volume and weight convert exactly.
How many grams are in a tablespoon of water?
One US tablespoon holds about 14.8 g, and one teaspoon about 4.94 g, since a tablespoon is 14.79 ml and a teaspoon 4.93 ml.
How many cups is 100 g of water?
100 grams of water is roughly 0.422 US cups. Weighing is more reliable than filling a cup, especially for liquids.
Where does this figure come from?
The density used here is 1.002 g/ml, based on NIST Handbook 133. Treat it as an approximation: real batches vary with brand, moisture and how the cup is filled.
