Convert between cups, tablespoons, teaspoons, fluid ounces, and milliliters – for example cups to tablespoons, teaspoons to milliliters, or fluid ounces to cups. Switch between the US and metric cup to match your recipe.
Usage Tip
For dry ingredients, weighing in grams is more accurate than measuring by volume.

Volume measurements at a glance
A cup is a fixed volume, so it always holds the same number of tablespoons and teaspoons – no matter what is in it.
Most common conversions
Cups to tablespoons
1 cup = 16 tablespoons. So 1/2 cup = 8 tbsp, 1/3 cup ≈ 5 1/3 tbsp, and 1/4 cup = 4 tbsp.
Tablespoons to teaspoons
1 tablespoon = 3 teaspoons. Half a tablespoon is 1 1/2 tsp – handy when a recipe only gives one of the two.
Cups to milliliters
1 US cup = 236.59 ml; a metric cup is 250 ml. So 1/2 US cup ≈ 118 ml and 1/4 cup ≈ 59 ml.
Fluid ounces to cups
8 fl oz = 1 cup, so 4 fl oz = 1/2 cup and 1 fl oz = 1/8 cup. These are fluid (volume) ounces, not weight ounces.
Liters to cups
1 liter = 4.23 US cups, or exactly 4 metric cups. So 500 ml is about 2.1 US cups.
US vs metric vs imperial cups
| Cup type | Volume |
|---|---|
| US customary cup | 236.59 ml |
| Metric cup (AU, NZ, EU) | 250 ml |
| Imperial cup (old UK) | 284 ml |
Recipes from different countries use different cups. The gap is small per cup but adds up across a recipe and matters most in baking. Use the cup standard toggle in the calculator above to match the recipe you are following.
