Newton to Horsepower Calculator

Convert force in newtons and velocity into horsepower.

Newton to HP Calculator
RESULT

Power is force times velocity. This calculator converts a force in newtons and a velocity in metres per second into power, expressed in both watts and horsepower.

Quick answer: Power (W) = Force (N) × Velocity (m/s), then HP = Watts ÷ 745.7. So 5,000 N at 20 m/s is 100,000 W, about 134 HP.

Newton to Horsepower Formula

Formula
HP = (Force [N] × Velocity [m/s]) ÷ 745.7
Force × velocity gives watts; divide by 745.7 for mechanical HP.

How to Use This Calculator

  1. Enter force in newtons.
  2. Enter velocity in metres per second.
  3. Read horsepower, with watts shown too.

Worked Example

Worked Example
P = 5000 N × 20 m/s = 100,000 W
HP = 100000 ÷ 745.7 = 134 HP

Frequently Asked Questions

Newtons alone can't convert to horsepower — you need velocity. Power (watts) = force × velocity, then divide watts by 745.7 for horsepower.

Because power is the rate of doing work. A force does no work, and produces no power, unless something is moving, so velocity is required.

A newton is the SI unit of force — the force needed to accelerate one kilogram at one metre per second squared. It's roughly the weight of a small apple.

Force × velocity already gives watts; divide by 1,000 for kilowatts. 100,000 W equals 100 kW.

Yes. Any force and the speed at which it acts gives power. It works for thrust, drawbar pull, or any applied force with a velocity.
