FAQ
What is the conversion factor from cal/s to ft·lbf/s?
1 cal/s equals 3.08596 ft·lbf/s. To convert, multiply the value in calories per second by 3.08596.
How do I convert 1 cal/s to ft·lbf/s?
1 cal/s = 3.08596 ft·lbf/s. For any value, multiply by 3.08596.
How do I convert ft·lbf/s back to cal/s?
Divide by the same factor — or equivalently, multiply by 0.3240483. So 1 ft·lbf/s = 0.324048 cal/s.
When would I need to convert calorie per second 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).
