Volume Converter

Where this converter helps

• Comparing metric liquid measurements with US customary or UK imperial values.
• Scaling recipes, containers, tanks, and packaging volumes.
• Checking whether a gallon value is US or UK before using it in a calculation.

Using the interface

Enter a value in any volume card and every supported unit updates. Litres are used as the base unit, which keeps metric, US customary, and UK imperial calculations consistent.

Practical notes

• US and UK gallons are different; choose the card that matches your source.
• Use millilitres for small recipes and lab work, litres for daily capacity, and cubic metres for large tanks or rooms.
• Fluid ounces here are US fluid ounces, not weight ounces.
