Power Converter
Convert power among W, kW, MW, mechanical hp, metric PS, and BTU/h.
How to use
- Enter the power and select the applicable source/target units among W, kW, MW, mechanical hp, PS, and BTU/h.
Capabilities and scope
Power is energy transfer per unit time. The converter uses watts as the reference and keeps the two horsepower definitions separate.
How it works
Reference factors are mechanical hp=745.699872 W, metric PS=735.49875 W, and BTU/h≈0.29307107 W.
Example
1 mechanical hp is about 0.7457 kW and is not exactly equal to 1 PS.
Useful for
- Compare motor ratings in hp and kW
- Check PS versus mechanical horsepower
- Convert thermal-load BTU/h into watts
Before you use it
- It does not model equipment efficiency or losses between electrical input and mechanical output.

Frequently asked questions
Are hp and PS the same horsepower?
No. Mechanical horsepower and metric horsepower (PS) are separate options with different factors.
