How to Convert Thrust to HP

Thrust and power are not directly related quantities, meaning there isn't a simple conversion factor to change from one unit of measurement into another. Thrust is a measurement of force on an object, usually measured in Newtons or pounds. Power is a measurement of work, or the amount of motion exerted on a body over the course of time by a force. Power is typically measured in units of horsepower (HP) or kilowatts. To convert from thrust (force) to horsepower requires you apply the distance moved and the time required.

Instructions

1. Use the basic relationship formula: Power = Force X (distance/time).

2. Divide the distance the object was moved (measured in feet) by the time it took to move it (measured in minutes.) This gives you a quotient measured in feet per minute.

3. Multiple the above quotient with the force (or thrust) applied to the object. The force should be measured in pounds. The resulting answer (power) is now in foot-pounds per minute.

4. Convert power to horsepower. One horsepower equals 33,000 foot-pounds per minute. So divide your power by 33,000 to change it to measurements of HP.
