Understanding power
Mechanical horsepower conventions
Power describes work done per unit time. The horsepower convention matters: this calculator uses mechanical horsepower, not metric horsepower or electrical efficiency assumptions.
How to verify a conversion
One mechanical horsepower is about 745.6998716 watts. Conversion of rated power does not measure actual power consumption or performance.
Source definitions: NIST Guide to the SI. See our conversion methodology for calculation and rounding details.
Accurate calculations, no guesswork
Every converter uses consistent unit definitions and returns an interactive result you can verify. For multiple measurements, use the batch converter.
