- 100,000 W
- Metric horsepower (PS)
- 135.9622 ch
- Mechanical horsepower (hp)
- 134.1022 hp
How it is calculated
- 1 PS (metric horsepower) = 735.49875 W.
- 1 hp (mechanical horsepower) = 745.69987 W.
- 1 BTU/h = 0.29307 W; 1 kcal/h = 1.163 W.
- We convert to watts first, then into each unit.
Example
100 kW = 135.96 PS = 134.10 hp.
Good to know
- Electrical horsepower (746 W) and boiler horsepower are not used here.
- Engine ratings depend on the test standard (SAE, DIN, ECE), not on the unit.
