How to use it
- Enter the amount (use decimals: ½ = 0.5).
- Choose the unit: cup, tbsp, tsp, fl oz, mL or g.
- Pick the ingredient.
- Read grams, milliliters, cups and spoons.
Why the ingredient matters
Cups measure volume, grams measure weight, and different ingredients pack a cup very differently. One US cup of water weighs about 237 g, but a cup of all-purpose flour is only about 125 g, and a cup of honey is about 340 g. That's why this converter asks for the ingredient: it multiplies the volume by a typical weight per cup.
Liquids are the easy case: for water, milk and similar liquids, milliliters and grams are nearly the same number. For anything powdery, chunky or sticky, the weight per cup is what makes the conversion work, and it varies more than most people expect. If your ingredient isn't in the list, pick the closest one by texture, or weigh one cup of it once and note the number.
Grams per US cup
| Ingredient | Grams per cup |
|---|---|
| All-purpose flour (spooned and leveled) | 125 g |
| Whole wheat flour | 120 g |
| Granulated sugar | 200 g |
| Powdered sugar | 120 g |
| Brown sugar (packed) | 213 g |
| Butter | 227 g |
| Vegetable oil | 218 g |
| Honey | 340 g |
| Milk | 244 g |
| Water | 237 g |
| Cocoa powder | 85 g |
| Rolled oats | 90 g |
| Uncooked rice | 185 g |
| Table salt | 288 g |
These are typical values for loose, normal measuring. A stick of butter (½ cup) is about 113 g.
US measuring units
| Unit | Equals | Milliliters |
|---|---|---|
| 1 cup | 16 tbsp | 236.6 mL |
| 1 tablespoon | 3 tsp | 14.8 mL |
| 1 teaspoon | — | 4.9 mL |
| 1 fluid ounce | 2 tbsp | 29.6 mL |
Australia and many metric recipes use a 250 mL cup and a 20 mL tablespoon (Australia) or 15 mL tablespoon (most others), and older British recipes may use a cup of about 284 mL. This tool always uses the US cup.
How you measure flour changes everything
Scooping flour straight from the bag packs it down, and a scooped cup can weigh 20% more than a cup that's spooned in and leveled. Many baking failures come from this. If a recipe gives grams, use a kitchen scale. If it only gives cups, spoon the flour into the cup, level it with a knife, and use the converter's value of 125 g per cup as a guide. Brown sugar is the opposite: recipes expect it packed firmly into the cup.
Converting European recipes
To bake a recipe written in grams with US measuring cups, choose g as the unit, pick the ingredient and read the cups and tablespoons. 250 g of flour is about 2 cups; 100 g of sugar is ½ cup. Expect small differences; for bread and pastry, a scale gives the most reliable results. For liquid volumes like quarts and gallons, use the gallons to liters converter. Everything runs in your browser.
