Fuel economy is the usual reason to convert, and it does not convert directly: miles per gallon and liters per 100 km are reciprocals of each other, so a higher number is better in one and worse in the other.

What a US gallon and a liter are
Both are units of volume, which is what makes them convertible at all: the converter above works by taking your value to a single reference unit for that family and back out again, so the figure it gives is the same one the table shows, carried to more digits. Nothing is sent anywhere to compute it — the arithmetic runs in this page, in your browser.
