FAQ
What is the conversion factor from PS to J/s?
1 PS equals 735.4987 J/s. To convert, multiply the value in metric horsepower by 735.4987.
How do I convert 1 PS to J/s?
1 PS = 735.499 J/s. For any value, multiply by 735.4987.
How do I convert J/s back to PS?
Divide by the same factor — or equivalently, multiply by 0.001359622. So 1 J/s = 0.00135962 PS.
When would I need to convert metric horsepower to joule per second?
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).
