How do you calculate horsepower example?
Horsepower Formula
- Horsepower (HP) = (Torque × Speed)/5252.
- Example 1.
- Determine the horsepower of a car which moves with a speed of 600 revolutions per minute and has a torque of 100 pound-foot.
- Solution:
- HP = 1.142 hp.
- Speed = (Horsepower × 5252)/ Torque.
- Speed = 18.17 revolutions per min.

What does watts and horsepower mean?
Horsepower (hp) is a unit of measurement of power (the rate at which work is done) It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
What is the power of 1 kW?
1000 watts
Detailed Solution. The Power equivalent to 1Kw is 1000 watts. A kilowatt is a unit of Electric Power.
How do you convert kW to power?
Here’s the Formula for Calculating Kilowatt-Hours Into Watts: watts = (kWh × 1,000) ÷ hrs.
How much hp is 1hp?

Which is bigger 1kw or 1hp?
Because 1 kW = 1,000 watts, 1 hp = 0.7457 kW. 1 kW = 1.337 hp.
How many kwh does a 1hp motor use?
It is 0.28kw or 280 watt.
How do you calculate horsepower of a motor?
Multiply the torque by the engine speed.
You will be using the formula (RPM * T) / 5252=HP, where RPM is the engine speed, T is the torque, and 5,252 is radians per second. The first calculation you want to do is multiply the torque and the engine speed.
How do I calculate what size electric motor I need?
Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.
