Frequently asked questions

Is mechanical HP different from metric HP?

Yes. 1 mechanical hp = 745.7 W. 1 metric hp (PS) = 735.5 W. Car specs in Europe use PS (Pferdestärke).

How many watts in a kilowatt?

1 kW = 1,000 W. Electric car motors are rated in kW; petrol engines in HP/PS.

What power unit do air conditioners use?

Cooling capacity is in BTU/h or kW. 1 ton of refrigeration = 12,000 BTU/h ≈ 3.517 kW.
