How to Convert Liters to Gallons

To convert a measurement in liters to a measurement in gallons, multiply the volume by the following conversion ratio: 0.264172 gallons/liter.

Since one liter is equal to 0.264172 gallons, you can use this simple formula to convert:

gallons = liters × 0.264172

The volume in gallons is equal to the volume in liters multiplied by 0.264172.

For example, here's how to convert 5 liters to gallons using the formula above.

gallons = (5 L × 0.264172) = 1.32086 gal

How Many Gallons Are in a Liter?

There are 0.264172 gallons in a liter, which is why we use this value in the formula above.
