# How do I calculate fuel consumption?

Fuel consumption is calculated by first adding up the distance travelled by car in relation to the fuel consumed. If you fill up your tank with 40 litres of petrol and use this to cover a distance of 600 kilometres, that means your average consumption per kilometre is 600 divided by 40, which is 15. As such, your car would be consuming 1 litre of petrol for every 15 kilometres travelled.
