About this conversion
This volume converter turns liter into us gallon using the exact defined relationship between the two units, not an approximation. A 10-liter fuel tank holds about 2.64 US gallons. The liter was introduced with the metric system in 1795 and is defined as exactly one cubic decimeter. The US gallon derives from an old English wine gallon measure, distinct from the larger imperial gallon used in the UK. Because both units are built on internationally standardized constants, the same liter-to-us gallon factor works whether you're doing a quick everyday estimate or a calculation that needs to be precise.
