FAQ
What is the conversion factor from W to ft·lbf/s?
1 W equals 0.7375621 ft·lbf/s. To convert, multiply the value in watts by 0.7375621.
How do I convert 1 W to ft·lbf/s?
1 W = 0.737562 ft·lbf/s. For any value, multiply by 0.7375621.
How do I convert ft·lbf/s back to W?
Divide by the same factor — or equivalently, multiply by 1.355818. So 1 ft·lbf/s = 1.35582 W.
When would I need to convert watt 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).
