g/hph to l/h (from grams/horsepower-hour to liters per hour)

Enter the specific fuel consumption in g / hph (gram/h.p.h., grams per horsepower-hour):

Enter engine power in hp (horsepower):

Enter the density of the fuel in kg / m3 (diesel – 860 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 / h.p.h 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 gram / hp) specific fuel consumption at power N.

N – (in hp) engine power

R – (kg / m3) fuel density
