FAQ

What is the conversion factor from BTU/min to kcal/hr?
1 BTU/min equals 15.11975 kcal/hr. To convert, multiply the value in British thermal units per minute by 15.11975.
How do I convert 1 BTU/min to kcal/hr?
1 BTU/min = 15.1197 kcal/hr. For any value, multiply by 15.11975.
How do I convert kcal/hr back to BTU/min?
Divide by the same factor — or equivalently, multiply by 0.06613868. So 1 kcal/hr = 0.0661387 BTU/min.
When would I need to convert British thermal unit per minute 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).
