Are hp and PS the same unit?

Similar but different. Mechanical horsepower (hp) is 745.7W; metric horsepower (PS) is 735.5W.

How many horsepower is 1 kW?

About 1.341 hp (mechanical) or about 1.360 PS.

Yes. 1 hp (mechanical) = 745.70 W while 1 PS (metric) = 735.50 W — about 1.4% apart, so the same number means slightly more power in hp.

BTU/h is a power unit for cooling capacity: 12,000 BTU/h ≈ 3.52 kW of cooling.

Power units are converted through watts (W). Automotive horsepower has two variants (mechanical hp and metric PS), while HVAC equipment uses BTU/h.

Unit	Symbol	In W	Common use
Watt	W	1 W	base unit
Kilowatt	kW	1,000 W	vehicles, motors
Megawatt	MW	1,000,000 W	power plants
Horsepower (mech.)	hp	745.70 W	US & UK cars
PS (metric hp)	PS	735.50 W	EU & Asia cars
BTU/hour	BTU/h	0.2931 W	AC capacity

Example: 150 PS to kW → 150 × 735.50 = 110,325 W → ÷ 1,000 = 110.3 kW. In mechanical hp it is about 148 hp — a slightly smaller figure.
