How to use the cooking converter
- Type a number in Amount: 1.5, 1,5, 1/2, 1 1/2 and ½ all work, or tap a fraction button.
- Choose the unit you have in From, from teaspoons to pounds.
- Pick the Ingredient. It only matters when you cross between volume and weight, such as cups to grams.
- If your recipe is not American, change Cup size.
- Read the headline, then the Volume and Weight boxes for every other unit.
How the conversion works
Volume units are exact US customary sizes. A US gallon is 3.785411784 L, so a cup is 236.5882365 mL, which equals 16 tablespoons, 48 teaspoons or 8 fluid ounces. An ounce by weight is 28.349523125 g and a pound is 453.59237 g. To cross from volume to weight, the tool multiplies milliliters by the ingredient's density, taken from the weight of one US cup of it. The cup weights below come from USDA FoodData Central household measures and the King Arthur Baking Ingredient Weight Chart.
| Ingredient | Weight of 1 US cup |
|---|---|
| Water | 236.6 g |
| Milk (whole) | 244 g |
| Vegetable oil | 218 g |
| Honey | 339 g |
| Maple syrup | 315 g |
| All-purpose flour | 125 g |
| Almond flour | 96 g |
| Cocoa powder (unsweetened) | 86 g |
| Rolled oats (dry) | 81 g |
| Sugar (granulated) | 200 g |
| Sugar (brown, packed) | 220 g |
| Sugar (powdered) | 120 g |
| Butter | 226.8 g |
| Rice (white, uncooked) | 185 g |
| Salt (table) | 288 g |
| Chocolate chips | 170 g |
Worked example with the default values
With 1 in Amount, Cup in From and All-purpose flour as the Ingredient, the headline reads 1 cup all-purpose flour = 125 g. The Volume box shows 48 tsp, 16 tbsp, 8 fl oz, 0.5 pint, 0.25 quart, 236.6 mL and 0.237 L. The Weight box shows 125 g, 0.125 kg, 4.41 oz and 0.276 lb.
Limits and edge cases
Cup weights are typical values, not guarantees: scooping packs in more flour than spooning and leveling, so for bread and cakes weigh it. The spoons are US sizes (4.93 and 14.79 mL), while an Australian tablespoon is 20 mL. Table salt is listed, and coarse kosher salt weighs much less per cup. Negative amounts are refused. To scale a whole recipe use the recipe scaler, for a missing ingredient try baking substitutions, and for other volume units use the volume converter.

Cooking converter FAQ
How many grams are in a cup of flour?
One US cup of all-purpose flour is about 125 g when spooned in and leveled, which is the figure this converter uses. King Arthur Baking uses 120 g, and scooping from the bag can pack in 150 g or more.
How many tablespoons are in a cup?
A US cup holds 16 tablespoons, which is also 48 teaspoons or 8 fluid ounces. Half a cup is 8 tablespoons and a quarter cup is 4 tablespoons.
Is a US cup the same as a metric cup?
No. A US customary cup is 236.6 mL, a metric cup is 250 mL, the US nutrition label cup is 240 mL and a Japanese cup is 200 mL. Pick the one your recipe uses in the Cup size menu.
How many grams are in a stick of butter?
One US stick of butter is half a cup, 8 tablespoons or 4 ounces, which is about 113 g. A full cup, or two sticks, is 226.8 g in this converter.
Is a fluid ounce the same as an ounce by weight?
No. A fluid ounce measures volume (29.57 mL) and an ounce by weight measures mass (28.35 g). Water comes closest, at about 1.04 oz per fluid ounce, while 8 fluid ounces of flour weigh only about 4.4 oz.
