FAQ
What is the conversion factor from PS to ft·lbf/s?
1 PS equals 542.476 ft·lbf/s. To convert, multiply the value in metric horsepower by 542.476.
How do I convert 1 PS to ft·lbf/s?
1 PS = 542.476 ft·lbf/s. For any value, multiply by 542.476.
How do I convert ft·lbf/s back to PS?
Divide by the same factor — or equivalently, multiply by 0.001843399. So 1 ft·lbf/s = 0.0018434 PS.
When would I need to convert metric horsepower to foot-pound force 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).
