Motor kW & HP Conversion Chart

Compare authored shaft-rating scenarios in kW, mechanical horsepower and metric horsepower. Preserve exact conversion without claiming standard motor availability.

QUICK LOOKUP

Search within the verified subset. Numeric sizes match complete designations; a nearby size is a candidate, not an exact match.

How to use this data

Mechanical hp=550 ft·lbf/s=745.6998715822702 W. Metric PS=75 kgf·m/s=735.49875 W. Keep shaft output distinct from electrical input.

    CHECK THE METHOD

    Worked example

    7.5 kW shaft power is about 10.0577 mechanical hp and 10.1972 PS; it is not exactly 10 hp.

    Common lookup questions

    What should I confirm before using this lookup?

    Mechanical horsepower, metric PS and electrical hp are distinct units. A converted number does not identify a stocked motor, frame size, efficiency or current.
