FAQ

What is the conversion factor from PS to kW?
1 PS equals 0.7354987 kW. To convert, multiply the value in metric horsepower by 0.7354987.
How do I convert 1 PS to kW?
1 PS = 0.735499 kW. For any value, multiply by 0.7354987.
How do I convert kW back to PS?
Divide by the same factor — or equivalently, multiply by 1.359622. So 1 kW = 1.35962 PS.
When would I need to convert metric horsepower to kilowatt?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
