Water Grams to Cups
One cup of water weighs 240 grams. Water is the reference point for every other ingredient — its density is almost exactly 1 gram per milliliter, so grams, milliliters, and the line on a measuring jug all line up.
Because 1 gram of water equals 1 milliliter, you can read a recipe’s water straight off a liquid measuring jug and be within a rounding error. A US cup is 237ml (about 237g); this page rounds to 240g for easy mental math. Temperature barely matters in the kitchen — water loses only about 4% of its weight per cup between room temperature and boiling.

Liquids compared by cup weight
Swapping one type for another changes the weight of a cup, so a recipe written in cups is not portable between them:
| Type | 1 cup | vs water |
|---|---|---|
| Water | 236g | — |
| Sourdough Starter | 227g | -9g |
| Vanilla Extract | 208g | -28g |
| Lemon Juice | 244g | +8g |
| Apple Cider Vinegar | 239g | +3g |
| Soy Sauce | 255g | +19g |
| Chicken Broth | 240g | +4g |
| Beef Broth | 240g | +4g |
| Vegetable Broth | 240g | +4g |
| Coconut Milk | 226g | -10g |
| Coconut Cream | 280g | +44g |
| Almond Milk | 244g | +8g |
Reading a cup of water accurately
Liquids are the easiest ingredient to measure by volume, but only if you read the jug at eye level: looking down at the cup from above can overstate a cup by a tablespoon or more. A cup of water weighs about 236g, so a kitchen scale is still the faster route when the recipe is already in grams.
