Engineering Principles & Calculations

This calculator uses the exact mathematical relationships between Power (Kilowatts / kW) to determine Horsepower (HP, Metric PS/CV). In practical installations, factors such as ambient raceway temperature, harmonic distortion, duty cycle continuous operation, and conductor impedance must be accounted for by a certified electrician.

Converts electrical or mechanical kilowatts to horsepower.

FAQ

Frequently Asked Questions

How do you convert kW to HP? +
Multiply kW by 1.341. For example, 7.5 kW × 1.341 = 10.06 HP.
How many HP is a 15 kW motor? +
15 kW × 1.34102 = 20.12 Horsepower (standard 20 HP motor equivalent).
Why does an EV with 150 kW feel so fast? +
150 kW translates to 201 Horsepower, but unlike combustion engines, electric motors deliver 100% of maximum torque instantly from zero RPM.
