Formula

Formula
BTU/min = cal/s × 0.23794

Multiply any value in calories per second by 0.23794 to obtain the value in British thermal units per minute.

Worked example

Convert 100 cal/s to BTU/min.

  1. 01Start with 100 cal/s.
  2. 02Multiply by the conversion factor: 100 × 0.23794 = 23.794 BTU/min.
Result100 cal/s = 23.794 BTU/min

FAQ

What is the conversion factor from cal/s to BTU/min?
1 cal/s equals 0.23794 BTU/min. To convert, multiply the value in calories per second by 0.23794.
How do I convert 1 cal/s to BTU/min?
1 cal/s = 0.23794 BTU/min. For any value, multiply by 0.23794.
How do I convert BTU/min back to cal/s?
Divide by the same factor — or equivalently, multiply by 4.20274. So 1 BTU/min = 4.20274 cal/s.
When would I need to convert calorie 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).
