Every unit below updates live from the value you enter in the "From" field above.
MPG and km/L both measure distance covered per unit of fuel, so a higher number means better efficiency in both — but L/100km measures the opposite way, fuel used per fixed distance, so a lower number is better there. That flip is why this is the one converter on this page where one unit (L/100km) uses a divide-based formula instead of a straight multiply — mixing the two without converting first is a common source of fuel-efficiency mix-ups.
