Volume Converter
Switch a volume between metric and US measures - handy when a recipe lists cups or tablespoons but your jug shows millilitres and litres.
About the Volume Converter
This tool converts a volume between metric and US customary measures, including millilitres, litres, cubic metres, teaspoons, tablespoons, cups, pints, quarts and gallons. It is especially handy in the kitchen, where recipes mix cups and spoons with millilitres and litres.
How to use it
- Enter the amount you know in its field, such as 250 in the millilitres field.
- Read off the equivalent in cups, tablespoons or fluid ounces.
- Convert tank, fuel or container volumes the same way using litres and gallons.
One important caveat: this converter uses US customary measures, so a US gallon is about 3.785 litres and a US cup is about 237 ml. UK imperial measures differ - an imperial gallon is about 4.546 litres - so check which system your recipe or fuel figure uses. For dry baking ingredients, volume does not equal weight, so a cup of flour and a cup of sugar weigh different amounts. Everything is computed in your browser and never uploaded.
Frequently asked questions
How many millilitres are in a cup?
A US customary cup is about 236.6 ml. Many recipes round this to 240 ml, and a metric cup used in some countries is exactly 250 ml, so check which standard your recipe follows.
How many litres are in a gallon?
A US gallon is about 3.785 litres, while an imperial (UK) gallon is about 4.546 litres. This converter uses the US gallon by default.
How many millilitres are in a tablespoon?
A US tablespoon is about 14.79 ml, usually rounded to 15 ml. A teaspoon is one third of that, roughly 5 ml.
Can I use this converter to weigh baking ingredients?
No, it only converts volume. Different ingredients have different densities, so a cup of flour weighs far less than a cup of sugar. Use a kitchen scale for accurate baking weights.
