Frequently asked questions
Which fuel economy units are handled?
It supports km/L, L/100km, US mpg, and UK mpg. US and UK mpg differ because their gallons differ, so pick the right one before comparing a car spec sheet.
Why does it reject zero?
L/100km is the inverse of km/L, so a zero or negative figure has no meaning and would divide by zero. Values must be greater than zero, and the conversion runs in your browser.
