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