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.
Converted Amount

In your chosen unitTHE MATH
amount × (unit volume in ml) ÷ (target unit in ml)
1 US cup = 236.59 ml · 1 metric cup = 250 ml · 1 tbsp = 14.79 ml · 1 tsp = 4.93 ml · 1 fl oz = 29.57 ml
Volumes use US tablespoons and teaspoons. The cup standard toggle switches only the cup between US (236.59 ml) and metric (250 ml).

Volume is not weight. Converting cups to grams needs the ingredient density – a cup of flour, sugar, and honey each weigh very different amounts. For weight-based results, use the Grams to Cups Converter or Ingredient Weight Converter linked below.
How cooking measurement conversion works
Cups, tablespoons, teaspoons, and fluid ounces are all units of volume – they measure the space an ingredient takes up, not its weight. Converting between them is straightforward because each unit has a fixed relationship to the others: a tablespoon is always three teaspoons, and a US cup is always sixteen tablespoons.
This converter turns your starting amount into milliliters, the base metric unit of volume, then divides into your target unit. That single base step is what lets you move freely between US and metric measures in one calculation.
The one thing volume cannot tell you is weight. Dense ingredients such as honey pack far more mass into a cup than light ones such as flour, so converting volume to grams requires knowing the specific ingredient and how it is packed.
