Conversion Formula
The formula to convert liters (l) to gallons (gal) is:
Gallons = Liters × 0.264172
This works because 1 liter equals approximately 0.264172 gallons. The conversion factor is derived from the volume relation between the metric system and the US customary units. You multiply the liters value by this factor to get gallons.
Example calculation for 1.5 liters:
- Start with 1.5 liters
- Multiply: 1.5 × 0.264172 = 0.396258 gallons
- Rounded to four decimals: 0.3963 gallons

Conversion Definitions
Liter (l): A liter is a metric unit for volume measurement, equal to one cubic decimeter or 1,000 cubic centimeters. It is widely used to measure liquids and gases in everyday life, science, and industry, representing a moderate volume for containers and quantities.
Gallon (gal): A gallon is a unit of volume commonly used in the United States and some other countries. The US liquid gallon equals 3.78541 liters. It’s often used to measure fuel, milk, and other liquids, where larger quantities than liters are practical for daily use.
Conversion FAQs
Why does the conversion factor from liters to gallons differ between countries?
There are multiple gallon definitions worldwide. The US liquid gallon used here equals about 3.785 liters, while the UK (imperial) gallon is bigger, roughly 4.546 liters. This causes the conversion factor to differ if you convert liters to imperial gallons instead of US gallons.
Can I use the same formula for converting liters to gallons for all liquids?
Yes, since both liters and gallons measure volume, the conversion applies regardless of the liquid type. However, density or weight differences won’t affect volume conversions, but may matter if you need mass instead.
Is it accurate to round the result to four decimals?
Rounding to four decimal places is usually enough for everyday use and typical measurements. For scientific or engineering purposes, more precision might be required, but for most practical purposes, four decimals provide a reliable balance between accuracy and simplicity.
Can I convert liters to gallons by dividing instead of multiplying?
Because the conversion factor is less than one, multiplying by 0.264172 converts liters to gallons directly. Dividing by the reciprocal (about 3.785) also works, but multiplication is more straightforward and less error prone.
Why does the conversion sometimes show negative values in charts?
Negative values represent volume below zero, which is theoretical or used in math contexts. In practical terms, volume cannot be negative, but charts may include negative numbers for completeness or calculations involving differences.
