Factors are entered by hand from NIST Handbook 130 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: litres to imperial gallons is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.

What is a liter?
One cubic decimeter. A liter of water weighs almost exactly one kilogram, which is how the unit was designed.
What is an imperial gallon?
Exactly 4.54609 liters since 1985, and the reason UK and US fuel economy figures cannot be compared: it is 20% larger than the US gallon, so 40 mpg in Britain is about 33 mpg in America on the same car.
How many imperial gallons are in a liter?
One liter is 0.21996925 imperial gallons. Going the other way, one imperial gallon is 4.54609 liters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
