Engine HorsePower Calculator
Need to estimate the engine horsepower of your vehicle? OkCalculator will be helping you without cost. This Engine Horsepower Calculator is designed to provide estimation for engine horsepower of your motor vehicle. The Engine Horsepower Calculator works on the basis of vehicle weight, time per quarter mile, and speed of your vehicle when finishing quarter file. ET Method and TrapSpeed Method is used by this Engine Horsepower Calculator.

The ET Method

The ET Method used by this Engine Horsepower Calculator uses the weight of your motor vehicle along with the time taken to finish quarter mile or 402.3 meters. The formula of horsepower in this method is:

Engine Horsepower = Weight / (ET/5.825)

Vehicle Weight

Weight of your motor vehicle. Input the weight in Pound, Ton, or Kilogram.

Time to Finish Quarter Mile (ET)

Keep the time to see how long it takes to finish a quarter mile or 402.3 meters. Specify the time elapsed in second, minute, hour, or day.

The TrapSpeed Method

In this method, you will require to find the weight of the vehicle and the speed of your vehicle when finishing a quarter mile. The formula to calculate horsepower under this method is:

Engine Horsepower = Weight x (Speed/234)
