Volume units
Volume is the space a substance occupies. The SI unit is the cubic meter, but the liter (one cubic decimeter) is used far more often. US and imperial units share names but not sizes: a US gallon is 3.785 liters while an imperial gallon is 4.546 liters.

What is the SI unit of volume?
This converter uses the cubic meter (m³) as its base unit. Volume is the space a substance occupies. The SI unit is the cubic meter, but the liter (one cubic decimeter) is used far more often. US and imperial units share names but not sizes: a US gallon is 3.785 liters while an imperial gallon is 4.546 liters.
Is a US gallon the same as a UK gallon?
No. A US gallon is 3.785 liters and an imperial (UK) gallon is 4.546 liters, about 20% more. US and UK pints and fluid ounces differ too.
How precise are the results?
Factors are the exact legal definitions where one exists (an inch is exactly 2.54 cm, a pound exactly 0.45359237 kg). Results show 10 significant digits by default; the precision menu offers 4 to 15.
Does the volume converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
