How to convert between cups, grams and ounces accurately
The reason a single “cup to grams” number never works is that a cup measures volume while grams measure weight. A cup of feathery flour holds far less mass than a cup of dense honey, so the only accurate way to convert between volume and weight is to use each ingredient’s density. This converter stores tested densities for dozens of common cooking and baking ingredients, so you get the right number every time.
Volume-to-volume (cups → tablespoons) and weight-to-weight (ounces → grams) conversions are fixed ratios and don’t depend on the ingredient. You only need to pick an ingredient when you cross between the two, for example cups to grams, or ounces to cups.
Common cup-to-gram weights
| Ingredient | 1 cup | ½ cup | ⅓ cup |
|---|---|---|---|
| Flour, all-purpose | 125 g | 63 g | 42 g |
| Flour, bread | 127 g | 64 g | 42 g |
| Sugar, granulated | 200 g | 100 g | 67 g |
| Sugar, brown (packed) | 220 g | 110 g | 73 g |
| Sugar, powdered | 120 g | 60 g | 40 g |
| Butter | 227 g | 114 g | 76 g |
| Cocoa powder | 85 g | 43 g | 28 g |
| Honey | 340 g | 170 g | 113 g |
| Water | 237 g | 119 g | 79 g |
Weights are spooned-and-levelled and based on commonly referenced King Arthur Baking and USDA densities. For the most reliable baking, weigh ingredients with a digital scale.
