Accepts numbers or expressions, e.g. 150 + 14.7
Result
cal/s
Rendered to 6 significant figures.
Formula
Formula
cal/s = kW × 239.0057
Multiply any value in kilowatts by 239.0057 to obtain the value in calories per second.
Worked example
Convert 100 kW to cal/s.
- 01Start with 100 kW.
- 02Multiply by the conversion factor: 100 × 239.0057 = 23900.6 cal/s.
Result100 kW = 23900.6 cal/s

FAQ
What is the conversion factor from kW to cal/s?
1 kW equals 239.0057 cal/s. To convert, multiply the value in kilowatts by 239.0057.
How do I convert 1 kW to cal/s?
1 kW = 239.006 cal/s. For any value, multiply by 239.0057.
How do I convert cal/s back to kW?
Divide by the same factor — or equivalently, multiply by 0.004184. So 1 cal/s = 0.004184 kW.
When would I need to convert kilowatt to calorie per second?
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).
