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

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, 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.
