To calculate gas per km: First, fill your tank and reset the trip meter. Drive normally until you need to refuel. At the next fill-up, note the kilometers driven from the trip meter and how many liters you added. Use the formula: Kilometers Driven ÷ Liters Used = Kilometers per Liter. Convert this to gas per km by taking the reciprocal: 1 ÷ Kilometers per Liter = Liters per Kilometer.
