Formula

Formula
BTU/min = kcal/hr × 0.06613868

Multiply any value in kilocalories per hour by 0.06613868 to obtain the value in British thermal units per minute.

Worked example

Convert 1000 kcal/hr to BTU/min.

  1. 01Start with 1000 kcal/hr.
  2. 02Multiply by the conversion factor: 1000 × 0.06613868 = 66.1387 BTU/min.
Result1000 kcal/hr = 66.1387 BTU/min

FAQ

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