FAQ

What is the conversion factor from PS to hp?
1 PS equals 0.9863201 hp. To convert, multiply the value in metric horsepower by 0.9863201.
How do I convert 1 PS to hp?
1 PS = 0.98632 hp. For any value, multiply by 0.9863201.
How do I convert hp back to PS?
Divide by the same factor — or equivalently, multiply by 1.01387. So 1 hp = 1.01387 PS.
When would I need to convert metric horsepower to mechanical horsepower?
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).
