Formula

Formula
MW = cal/s × 4.184e-6

Multiply any value in calories per second by 4.184e-6 to obtain the value in megawatts.

Worked example

Convert 1.00000e+6 cal/s to MW.

  1. 01Start with 1.00000e+6 cal/s.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 4.184e-6 = 4.184 MW.
Result1.00000e+6 cal/s = 4.184 MW

FAQ

What is the conversion factor from cal/s to MW?
1 cal/s equals 4.184e-6 MW. To convert, multiply the value in calories per second by 4.184e-6.
How do I convert 1 cal/s to MW?
1 cal/s = 4.184e-6 MW. For any value, multiply by 4.184e-6.
How do I convert MW back to cal/s?
Divide by the same factor — or equivalently, multiply by 239005.7. So 1 MW = 239006 cal/s.
When would I need to convert calorie per second to megawatt?
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).
