Formula
Formula
PS = J/s × 0.001359622
Multiply any value in joules per second by 0.001359622 to obtain the value in metric horsepower.
Worked example
Convert 1000 J/s to PS.
- 01Start with 1000 J/s.
- 02Multiply by the conversion factor: 1000 × 0.001359622 = 1.35962 PS.
Result1000 J/s = 1.35962 PS

FAQ
What is the conversion factor from J/s to PS?
1 J/s equals 0.001359622 PS. To convert, multiply the value in joules per second by 0.001359622.
How do I convert 1 J/s to PS?
1 J/s = 0.00135962 PS. For any value, multiply by 0.001359622.
How do I convert PS back to J/s?
Divide by the same factor — or equivalently, multiply by 735.4988. So 1 PS = 735.499 J/s.
When would I need to convert joule per second to metric 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).
