Conversion Formula
The formula to convert litres to gallons is:
Gallons = Litres × 0.264172
This works because one litre equals approximately 0.264172 US gallons. So when you multiply a volume in litres by this number, you’re changing the unit from litres to gallons. The factor 0.264172 comes from the fixed volume relationship between the metric and US customary systems.
For example, converting 25 litres:
- Multiply 25 litres × 0.264172 gallons/litre
- 25 × 0.264172 = 6.6043 gallons
- This means 25 litres is equal to 6.6043 gallons

Conversion Definitions
Litres: A litre is a metric unit of volume equal to one cubic decimeter (dm³), or 1,000 cubic centimeters (cm³). It is commonly used to measure liquids and fluids, such as water, milk, or fuel. The litre is part of the metric system and widely used worldwide for everyday volume measurements.
Gallons: A gallon is a unit of volume used in US customary and imperial measurement systems. The US liquid gallon equals 3.78541 litres. Gallons are often used for fuel, milk, and other liquid quantities primarily in the United States. The UK gallon is slightly larger, about 4.54609 litres.
Conversion FAQs
Can I convert litres to gallons using this tool for any volume?
Yes, the provided conversion tool accepts any numeric input and converts litres to gallons based on the fixed factor of 0.264172. However, the tool assumes US gallons; if you need UK gallons, a different conversion factor is necessary.
Why does the conversion give a decimal number instead of a whole number?
Because litres and gallons are different units with unique sizes, converting between them often results in fractional values. One litre is not equal to a whole gallon, so decimal results represent the exact equivalent volume in gallons.
Is the conversion factor 0.264172 exact?
The factor 0.264172 is a rounded constant representing the US liquid gallon; the precise value is 0.264172052. For most practical purposes, rounding to six decimal places is sufficient, but very high-precision calculations might require more decimal digits.
How does temperature affect the conversion between litres and gallons?
Volume measurements can change with temperature due to fluid expansion or contraction. Both litres and gallons measure volume, so the conversion factor remains constant, but the actual liquid volume can vary slightly if temperature fluctuates significantly.
Can I convert gallons back to litres using the same formula?
To convert gallons back to litres, you would use the inverse of the factor: multiply gallons by approximately 3.78541. The formula is Litres = Gallons × 3.78541, which reverses the conversion process.
