Тhis calculator will measure the approximate horsepower.
WHP to HP conversion. Convert Wheel Horsepower to Horsepower, Front Wheel Drive (FWD), Rear Wheel Drive (RWD), All Wheel Drive (AWD), Four Wheel Drive (4WD), Crank HP, Engine Horsepower etc. This information should be used as a rough guide only. There’s factors outside of the vehicle itself that also affect horsepower. Humidity, altitude, and temperature all have an effect on engine performance. Total power lost is specific to each vehicle and therefore no single rule, percentage, or fixed number could possibly apply to all vehicles.
