The Volume Conversion Calculator converts any volume measurement between metric, imperial, and household units — useful in chemistry, cooking, engineering, and everyday calculations. Enter your value to convert, then select your From and To units — spanning mL, L, m³, cm³, gallons, quarts, pints, fluid ounces, cups, and barrels — to get the converted volume along with the conversion formula used.

Conversion Formula

To convert milliliters to liters, divide by 1000. Since 1 liter = 1000 milliliters, the conversion is: volume in liters = volume in mL ÷ 1000.
US gallons are smaller than Imperial gallons. 1 US gallon equals 3.785 liters, while 1 Imperial gallon equals 4.546 liters. Imperial gallons are used in the UK and some Commonwealth countries.
One milliliter is exactly equal to one cubic centimeter (1 mL = 1 cm³). These units are equivalent and can be used interchangeably in most contexts.
Use exact conversion factors rather than rounded values. For example, 1 US gallon = 3.785411784 liters exactly. Maintain precision throughout calculations and round only the final result.
To convert cubic meters to liters, multiply by 1000. Since 1 cubic meter = 1000 liters, the conversion is: volume in liters = volume in m³ × 1000.
Barrels are commonly used in the petroleum industry. A petroleum barrel equals 42 US gallons or approximately 159 liters. Different types of barrels (petroleum, US fluid, Imperial) have different volumes.
