UnitConVolume
Volume measures the amount of three-dimensional space a substance or container occupies. The SI unit of volume is the cubic meter, but liters and milliliters are more common in practice. Volume conversions appear in cooking, chemistry, medicine, fuel measurement, and packaging. This converter includes both US and UK liquid units because gallons and pints are not the same in both systems.

Frequently asked questions
It depends on which gallon you mean. A US gallon is 3.78541 liters, while a UK imperial gallon is 4.54609 liters.
The UK gallon is larger than the US gallon. That difference affects related units such as pints, quarts, and fluid ounces as well.
A liter is about 4.22675 US cups. If you are using metric cooking references, always confirm whether the recipe assumes US, imperial, or metric cup sizes.
In US customary cooking, 1 tablespoon equals 3 teaspoons. This is one of the most common kitchen conversions.
Divide milliliters by 29.5735 to get US fluid ounces. For UK fluid ounces, use the imperial conversion instead.
