Convert g/kWh to l/h (from gram per kWh to liters per hour) fuel calculator

Enter the specific fuel consumption in g/kWh (grams per kilowatt hour):

Enter the engine power in kW:

Enter the density of the fuel in kg/m3 (references: diesel – 850 kg/m3, gasoline (petrol) – 710 kg/m3):

Fuel consumption liters per hour (l/h) is:


How to calculate fuel consumption in liters per hour, if the specific consumption in g / kWh is known?

You can calculate by the formula:

Q = N * q / R, where

Q – (in l / h) maximum theoretical fuel consumption in grams per 1 hour of engine operation at maximum power;

q – (in g / kWh) specific fuel consumption for power N;

N – (in kW) engine power;

R – (kg / m3) fuel density.

Diesel fuel density: 820 – 860 kg / m3

Gasoline (petrol) fuel density: 710 – 760 kg / m3
