Examples

0110 km/l = 10 l/100 km

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

mpg and l/100 km move in opposite directions. Higher mpg means lower consumption; higher l/100 km means higher consumption.

03Base unit: l/100 km

Fuel units are normalised through litres per 100 kilometres; mpg and km/l are inverse values.
