Enter the total thrust and the velocity of a vehicle into the calculator to determine the total equivalent horsepower.

Thrust to Horsepower Formula

The following formula can be used to convert total thrust to total horsepower.

HP = T * V / 375
  • Where HP is the horsepower
  • T is the thrust in pound-force
  • V is the velocity in miles per hour

To calculate the horsepower from thrust, multiply the thrust by the velocity, then divide by 375.

Thrust to Horsepower Definition

Converting a thrust to a horsepower involves multiplying the total pound-force of thrust by the velocity of the object.

Thrust to Horsepower Example

How to convert a thrust to horsepower?

The first step in calculating horsepower from thrust is to measure the total thrust the engine can output or is current outputting during the time of movement.

In this example, the total thrust is measured to be 5000 lb-force.

The next step is to measure the maximum velocity of the vehicle during the time that that thrust is being supplied by the engine.

In this case, the maximum velocity is measured to be 60 MPH.

Finally, using the formula above, calculate the total estimated horsepower given the thrust and maximum velocity provided.

HP = T * V / 375

HP = 5000 * 60 / 375

HP = 800 HP


What is horsepower?

Horsepower is defined as a unit of power that is equal to 550 foot-pounds per second.
