For example, to convert 15 liters to gallons:
- Start with 15 liters.
- Multiply 15 by 0.264172.
- 15 × 0.264172 = 3.96258 gallons.
- Rounded to 4 decimal places, that is 3.9626 gallons.
Conversion Example
- Convert 25 liters to gallons:
- Multiply 25 × 0.264172.
- 25 × 0.264172 = 6.6043 gallons.
- So, 25 l equals 6.6043 gallons.
- Convert 7.5 liters to gallons:
- Calculate 7.5 × 0.264172.
- 7.5 × 0.264172 = 1.98129 gallons.
- This means 7.5 l is about 1.9813 gallons.
- Convert 0 liters to gallons:
- 0 × 0.264172 = 0 gallons.
- Zero liters equals zero gallons.
- Convert 50 liters to gallons:
- Multiply 50 × 0.264172.
- 50 × 0.264172 = 13.2086 gallons.
- Therefore, 50 l equals 13.2086 gallons.

Conversion Definitions
l (liter): A liter is a metric unit measuring volume, equal to one cubic decimeter (dm³). It’s widely used worldwide for liquids, like water, fuel, or beverages. One liter contains 1,000 cubic centimeters, and is slightly more than a quart in US measurements.
gallons: Gallon is a volume unit used mainly in the US and UK, but their sizes differ. The US liquid gallon equals 3.78541 liters, used for fuel and liquids. The UK gallon is larger, about 4.54609 liters. Here, US gallons are referenced for conversion.
Conversion FAQs
Why is the gallon value smaller than liters when converting?
Because one gallon contains more volume than one liter, the numeric value in gallons will be less when converting from liters. Since 1 liter equals about 0.264172 gallons, the gallon number is smaller than the liter number for the same volume.
Can I convert liters to gallons using a simple multiplication only?
Yes, since the conversion factor between liters and gallons is constant, multiplying the liters by 0.264172 gives the gallon equivalent directly. No additional steps or adjustments are needed unless converting between US and UK gallons.
Does temperature affect liter to gallon conversion?
The conversion factor itself is fixed; however, the volume of liquids can change slightly with temperature due to expansion or contraction. The conversion assumes standard conditions, so for precise scientific work, temperature effects might be considered.
Are gallons and liters measuring the same type of volume?
Both measure liquid volume but come from different measurement systems. Liters belong to the metric system, while gallons are part of the imperial or US customary systems. Despite differences, they both quantify how much space a liquid occupies.
Why does the conversion factor differ between US and UK gallons?
Because US and UK gallons were defined independently historically, their sizes vary. The US gallon is based on the wine gallon used in the 18th century, while the UK gallon is based on the volume of 10 pounds of water. This results in different liter equivalents.
