Cooking Measurement Converter
1 cup equals 8 fluid ounces, and 1 cup of all-purpose flour weighs about 120 grams. This cooking measurement converter switches between cups, tablespoons, teaspoons, fluid ounces, milliliters, and grams. Pick your ingredient for gram conversions, since different ingredients have different weights per cup.
Quick answer
Volume conversions (cups, tablespoons, teaspoons, fluid ounces, milliliters) are exact.
What this tells you
- •Volume conversions (cups, tablespoons, teaspoons, fluid ounces, milliliters) are exact.
- •Gram conversions use average ingredient density in grams per cup.
- •Results are rounded to 4 decimal places for readability.
How to Use

- 2Select the unit you are converting from.
- 3Select the unit you are converting to.
- 4If grams are involved, pick the ingredient so the converter uses the right density.
- 5Click Convert to get the result.
How It Works
Formula
Volume to volume: converted = input x (source-to-cup factor) / (target-to-cup factor). Weight to volume: cups = grams / density (g per cup).The converter first normalizes the input to cups using fixed volume factors. For gram conversions it divides or multiplies by the selected ingredient density, measured in grams per cup.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Cups to fluid ounces
1 cup x 8 = 8 fluid ounces. This is a fixed volume conversion that does not depend on the ingredient.
Grams to cups (all-purpose flour)
All-purpose flour weighs about 120 g per cup. Divide 240 by 120 to get 2 cups.
Tablespoons to teaspoons
1 tablespoon equals 3 teaspoons. Multiply 3 x 3 to get 9 teaspoons.
Common Cooking Measurement Conversions
Standard US cooking measurement relationships and average ingredient weights per cup.
| Amount | Equals | Grams (by ingredient) |
|---|---|---|
| 1 cup | 8 fl oz, 16 tbsp, 48 tsp, 237 ml | Flour 120 g, Sugar 200 g, Butter 227 g |
| 1 tablespoon | 3 tsp, 0.5 fl oz, 15 ml | Flour 7.5 g, Sugar 12.5 g, Butter 14.2 g |
| 1 fluid ounce | 2 tbsp, 6 tsp, 30 ml | Flour 15 g, Sugar 25 g, Butter 28.4 g |
| 1 teaspoon | 0.33 tbsp, 5 ml | Flour 2.5 g, Sugar 4.2 g, Butter 4.7 g |
Gram values are averages. Actual weight varies by brand, grind, and how tightly the ingredient is packed.
Common mistakes
- Scooping flour directly from the bag packs it down and gives you up to 30 percent more than 120 g per cup. Spoon flour into the cup and level it off with a knife.
- Brown sugar is measured packed, while powdered sugar is measured unsifted unless the recipe says otherwise.
- Fluid ounces measure volume, not weight. Do not confuse them with ounces by weight, which are used for solid ingredients.
