Formula

Formula
BTU/min = ft·lbf/s × 0.07710405

Multiply any value in foot-pounds force per second by 0.07710405 to obtain the value in British thermal units per minute.

Worked example

Convert 100 ft·lbf/s to BTU/min.

  1. 01Start with 100 ft·lbf/s.
  2. 02Multiply by the conversion factor: 100 × 0.07710405 = 7.7104 BTU/min.
Result100 ft·lbf/s = 7.7104 BTU/min

FAQ

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