FAQ

What is the conversion factor from ft·lbf/s to kcal/hr?
1 ft·lbf/s equals 1.165794 kcal/hr. To convert, multiply the value in foot-pounds force per second by 1.165794.
How do I convert 1 ft·lbf/s to kcal/hr?
1 ft·lbf/s = 1.16579 kcal/hr. For any value, multiply by 1.165794.
How do I convert kcal/hr back to ft·lbf/s?
Divide by the same factor — or equivalently, multiply by 0.8577848. So 1 kcal/hr = 0.857785 ft·lbf/s.
When would I need to convert foot-pound force per second to kilocalorie per hour?
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).
