# How Many Liters Are in a Gallon?

## Conversion Formulas

Convert liters to gallons and gallons to liters using our conversion chart, conversion calculator, and learn the relationship between these two units.

Conversion of liters to gallons and gallons to liters is an easy one since both units are units of volume. Just be aware that there are three gallons in general use including US liquid gallon, US dry gallon, and Imperial gallon. A liter is a metric system unit of volume and is equal to 1 cubic decimeter (dm3), 1000 cubic centimeters (cm3), or 0.001 cubic meters (m3).

One liter occupies a volume of 0.1m x 0.1m x 0.1m and thus equals to one-thousandth (0.001 m3) of a cubic meter.

Thus, gallons-liter conversion formulas are:

1 US Liquid Gallon = 128 US Fluid Ounces (fl oz) = 3.78541 liters

1 US Dry Gallon = 148.95 US Fluid Ounces (fl oz) = 4.4049 liters

1 Imp Liquid Gallon = 160 Imp Fluid Ounces = 4.54609 liters

In most situations, US liquid gallons are used for liter to gallon and gallon to liter conversions.

## Conversion Examples

If You have 2 gallons (US/Imp) that would be:

V(liters) = 3.78541 * V(US fluid gallon) = 3.78541 * 2 = 7.57082 liters

V(liters) = 4.4049 * V(US dry gallon) = 4.4049 * 2 = 8.8098 liters

V(liters) = 4.54609 * V(Imp gallon) = 4.54609 * 2 = 9.09218 liters
