Formula
Formula
kW = kcal/hr × 0.001163
Multiply any value in kilocalories per hour by 0.001163 to obtain the value in kilowatts.
Worked example
Convert 10000 kcal/hr to kW.
- 01Start with 10000 kcal/hr.
- 02Multiply by the conversion factor: 10000 × 0.001163 = 11.63 kW.
Result10000 kcal/hr = 11.63 kW

FAQ
What is the conversion factor from kcal/hr to kW?
1 kcal/hr equals 0.001163 kW. To convert, multiply the value in kilocalories per hour by 0.001163.
How do I convert 1 kcal/hr to kW?
1 kcal/hr = 0.001163 kW. For any value, multiply by 0.001163.
How do I convert kW back to kcal/hr?
Divide by the same factor — or equivalently, multiply by 859.8452. So 1 kW = 859.845 kcal/hr.
When would I need to convert kilocalorie per hour to kilowatt?
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).
