Why 1 US Gallon Equals 3.78541 Liters
The conversion factor holds because both units are expressed in the same base unit, the cubic meter. Dividing their definitions in that base unit gives the exact factor.
Definition
The US liquid gallon and the liter are both defined as volumes in the cubic meter (m3). The conversion factor is derived by comparing these definitions directly.
Principle
The principle is to express both the US gallon and the liter in the cubic meter, then cancel the cubic meter to find how many liters equal one US gallon.
Assumptions
- The conversion uses the defined factor for the US liquid gallon.
- The conversion uses the defined factor for the liter.
- The base unit for both is the cubic meter.
Cautions
- This conversion depends on a specific unit definition or physical assumption. Check the context before using it in reports.
