How the conversion works
Divide liters by 3.785411784. The widget starts at 10 liters; adjust it and press Convert. The comparison grid shows US pints and cups alongside, which share the same US-gallon family.
US versus Imperial gallons
The Imperial gallon is 4.54609 liters — about 20% larger. A mileage figure in miles-per-Imperial-gallon cannot be compared directly with miles-per-US-gallon. This converter labels both explicitly.
Keep in mind
- Volume only: a fluid ounce is not interchangeable with a mass ounce.
- Container brim capacity and usable capacity differ; the converter handles units, not packaging.
