How to Use the Liters to Gallons Converter
Enter a volume in liters to convert it to US gallons for fuel, containers, liquids and everyday volume comparisons.
Practical Example
20 L ÷ 3.785411784 ≈ 5.2834 US gallons.
Factors That Affect the Result
The conversion factor is fixed, but make sure the target is a US gallon. The imperial gallon used in the UK is larger and gives a different result.
Frequently Asked Questions
How many liters are in one US gallon?
One US gallon equals 3.785411784 liters.
How many gallons is 10 liters?
10 liters is about 2.6417 US gallons.
Is a US gallon the same as an imperial gallon?
No. An imperial gallon is larger.
Converting Liters to US Gallons
Liters measure volume in the metric system, while the US liquid gallon is a customary volume unit. One US gallon equals exactly 3.785411784 liters, so liters can be converted to US gallons by dividing by that value. For example, 10 liters is about 2.64 US gallons. Be careful because the imperial gallon used in some contexts is larger than the US gallon and requires a different conversion factor. This distinction matters for fuel economy, tank capacity and liquid quantities. The conversion changes the unit only and does not account for temperature-related volume changes in precision measurement. When reading specifications, verify whether “gal” means US or imperial gallons before calculating, and round the result to a level appropriate for the accuracy of the source measurement.
Conversion Formula and Context
US liquid gallons and Imperial gallons are different. One US liquid gallon equals exactly 3.785411784 liters, so confirm the gallon convention before converting volume specifications.
