Volume Converter
Convert volume between metric and US units, from milliliters to gallons.
Converting volume step by step
Put in your quantity, pick the unit you are working from, and choose the one you need. The figure recalculates with each keystroke, and the swap button reverses the pair when a recipe gives you one unit but your jug is marked in another.
Alongside metric liters and milliliters you will find the US kitchen measures: teaspoons, tablespoons, cups, pints, quarts, and gallons. The cubic meter rounds things out for larger volumes like tanks or rainfall.

A note on cups, ounces, and gallons
Volume units carry a famous catch: the measures here are US customary, and they are not the same as their imperial cousins used in the UK. A US gallon is about 3.79 liters while an imperial gallon is roughly 4.55, so a recipe's origin matters before you start pouring.
For dry baking ingredients, remember that a cup measures space, not mass. A cup of flour and a cup of sugar fill the same volume but weigh differently, which is why bakers chasing precision often switch to a scale and the weight converter instead.
Frequently asked questions
- How many milliliters are in a cup?
- A US cup holds 236.588 milliliters, usually rounded to 240 ml in recipes. If you are following a metric recipe, a 250 ml metric cup is slightly larger.
- How many tablespoons are in a cup?
- There are 16 US tablespoons in a US cup. That also means 8 fluid ounces, since one fluid ounce equals two tablespoons.
- Is a US gallon the same as a UK gallon?
- No. A US gallon is about 3.785 liters and an imperial (UK) gallon is about 4.546 liters. This converter uses US customary units, so check which system a recipe or fuel figure refers to.
- How do I convert liters to gallons?
- Divide the liters by 3.78541 to get US gallons. So 10 liters is about 2.64 gallons. The swap button handles the reverse direction automatically.
- Can I use this for dry ingredients?
- It converts the volume itself, which works for liquids directly. Dry ingredients like flour fill a volume but vary in weight, so for baking accuracy a kitchen scale and weight conversion are more reliable.
