Before you rely on it
US liquid gallons by default
This page converts to the US liquid gallon: 1 US gallon is exactly 3.785411784 liters.
The UK Imperial gallon is larger, about 4.54609 liters. A car that takes 50 liters of fuel is about 13.2 US gallons but only about 11 Imperial gallons, so the label matters.
"Litre" and "liter" are the same unit, spelled differently.
The gallon is exactly 3.785411784 liters, but the reverse factor, about 0.264172, never ends — so answers on this page are rounded. For a rough figure, divide liters by 4; that runs about 5 percent low.
