Conversion Formula
The formula to convert liters to gallons is:
Gallons = Liters × 0.264172
This works because one liter is defined as exactly 1 cubic decimeter, and one US liquid gallon equals 3.78541 liters. So dividing 1 by 3.78541 equals approximately 0.264172. Multiplying liters by this number converts liters into gallons correctly.
Example:
Convert 9 liters to gallons:
- Multiply 9 liters by 0.264172
- 9 × 0.264172 = 2.377548
- Rounded to four decimal places: 2.3776 gallons
Conversion Example
- Convert 5 liters to gallons:
- Multiply 5 × 0.264172
- Result: 1.32086 gallons
- Rounded: 1.3209 gallons
- Convert 12.5 liters to gallons:
- 12.5 × 0.264172
- Result: 3.30215 gallons
- Rounded: 3.3022 gallons
- Convert 0 liters to gallons:
- 0 × 0.264172
- Result: 0 gallons
- Convert 20 liters to gallons:
- 20 × 0.264172
- Result: 5.28344 gallons
- Rounded: 5.2834 gallons

Conversion Definitions
Liters: A liter is a metric unit of volume, defined as the volume occupied by a cube measuring 10 centimeters on each side. It is commonly used worldwide to measure liquids and gases, especially in scientific and everyday contexts, such as in food packaging and fuel quantities.
Gallons: A gallon is a unit of volume used primarily in the United States and some other countries, especially for liquids like gasoline and milk. The US liquid gallon equals about 3.785 liters, while the UK (imperial) gallon is about 4.546 liters, so they are different units despite sharing the name.
Conversion FAQs
Why is the conversion factor 0.264172 used for liters to gallons?
This number comes from dividing one liter by one US liquid gallon, which is approximately 3.78541 liters. The exact conversion factor is 1 ÷ 3.78541 = 0.264172. Using this factor converts liters to US gallons accurately.
Can I convert liters to gallons without a calculator?
You can estimate by remembering that 1 liter is about 1/4 of a gallon (0.264). Multiplying liters by 0.25 gives you a rough gallons value, close enough for casual use, but for precision, the exact factor 0.264172 is better.
Is the gallon value the same in all countries?
No, the US gallon differs from the UK gallon. The US liquid gallon is about 3.785 liters, while the UK (imperial) gallon equals about 4.546 liters. So converting liters to gallons depends on which gallon standard you need.
What happens if I convert negative liters?
Negative liters might represent reverse flow or a decrease in volume. The conversion formula holds the same, producing negative gallons. However, in practical terms, volume cannot be negative, but the math remains consistent.
Does temperature affect the liters to gallons conversion?
The conversion is based on volume units and remains constant regardless of temperature. But since liquids expand or contract with temperature changes, the actual volume may differ slightly in practice, though the conversion factor stays the same.
