| 1/4 cup | 59.3 g | 2.09 oz |
| 1/3 cup | 79 g | 2.79 oz |
| 1/2 cup | 119 g | 4.18 oz |
| 2/3 cup | 158 g | 5.57 oz |
| 3/4 cup | 178 g | 6.27 oz |
| 1 cup | 237 g | 8.36 oz |
| 1 1/2 cups | 356 g | 12.5 oz |
| 2 cups | 474 g | 16.7 oz |
| 3 cups | 711 g | 25.1 oz |
| 1 tbsp | 14.8 g | 0.52 oz |
| 2 tbsp | 29.6 g | 1.04 oz |
| 1 tsp | 4.9 g | 0.17 oz |
| 1/2 tsp | 2.5 g | 0.09 oz |
Each row is USDA’s 1-cup weight (237 g) times the amount. A tablespoon is 1/16 cup and a teaspoon is 1/48 cup, so 1 tbsp = 237 ÷ 16 = 14.8 g. Ounces are grams ÷ 28.3495.
Water grams to cups
| Weight | Cups | Closest measure |
|---|---|---|
| 25 g | 0.11 | 1 tbsp + 2 tsp |
| 50 g | 0.21 | 3 tbsp + 1 1/4 tsp |
| 100 g | 0.42 | 1/3 cup + 1 tbsp + 1 1/4 tsp |
| 200 g | 0.84 | 3/4 cup + 1 tbsp + 1 1/2 tsp |
| 250 g | 1.05 | 1 cup + 2 3/4 tsp |
| 500 g | 2.11 | 2 cups + 1 tbsp + 2 1/4 tsp |
Cups = grams ÷ 237. The last column rounds to the nearest 1/4 teaspoon using a standard set of cups and spoons.

Measuring water by the cup
Measure liquids in a liquid measuring cup set on a level surface, and read the line at eye level, as NIST suggests.
