FAQ

What is the conversion factor from BTU/min to ft·lbf/s?
1 BTU/min equals 12.96949 ft·lbf/s. To convert, multiply the value in British thermal units per minute by 12.96949.
How do I convert 1 BTU/min to ft·lbf/s?
1 BTU/min = 12.9695 ft·lbf/s. For any value, multiply by 12.96949.
How do I convert ft·lbf/s back to BTU/min?
Divide by the same factor — or equivalently, multiply by 0.07710405. So 1 ft·lbf/s = 0.077104 BTU/min.
When would I need to convert British thermal unit per minute 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).
