Cooking Measurement Converter
Convert between teaspoons, tablespoons, cups, fluid ounces, milliliters, and liters.
How the conversion works
Every unit here is converted through milliliters. Multiply your amount by the milliliters in its unit, then divide by the milliliters in the unit you want. These are US customary measures, where one cup is 236.5882 ml.
Worked example
A recipe needs 2.5 cups of stock and you only have a tablespoon. First, 2.5 × 236.5882 = 591.4706 ml. Then divide by the 14.7868 ml in a tablespoon: that is exactly 40 tablespoons.

Common cooking conversions
- 3 teaspoons = 1 tablespoon
- 16 tablespoons = 1 cup = 8 fluid ounces
- 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon
- 1 US cup ≈ 237 ml (a metric 'cup' used in some countries is a rounder 250 ml — close, but not identical)
A note on weight vs. volume
This converter handles volume measurements only (teaspoons, cups, milliliters, etc.). Converting a cup of an ingredient to grams isn't a fixed ratio — it depends on the ingredient's density: a cup of flour weighs roughly 120g, a cup of granulated sugar about 200g, and a cup of butter about 227g, all quite different for the same 'cup' of volume. For weight-based recipe conversions, look up the specific ingredient rather than treating cups as a universal weight unit.
Frequently asked questions
Is a US cup the same as a UK or metric cup?
No. A US cup is about 237 ml, a metric cup (used in Australia, New Zealand, and some recipe books) is a rounder 250 ml, and the UK doesn't use standardized 'cup' measurements in the same way — UK recipes typically use weight (grams) instead. This converter uses US customary measurements throughout.
Why can't this tool convert cups to grams?
Grams measure weight and cups measure volume — converting between them requires knowing the ingredient's density, which is different for flour, sugar, butter, liquids, and so on. A cup of feathers and a cup of lead take up the same volume but weigh very differently.
