J/stoMW

Convert joules per second (J/s) to megawatts (MW).

Factor1 J/s = 1e-6 MW

Converter

J/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1MW

Rendered to 6 significant figures.

Formula

Formula
MW = J/s × 1e-6

Multiply any value in joules per second by 1e-6 to obtain the value in megawatts.

Worked example

Convert 1.00000e+6 J/s to MW.

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

FAQ

What is the conversion factor from J/s to MW?
1 J/s equals 1e-6 MW. To convert, multiply the value in joules per second by 1e-6.
How do I convert 1 J/s to MW?
1 J/s = 1e-6 MW. For any value, multiply by 1e-6.
How do I convert MW back to J/s?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 MW = 1.00000e+6 J/s.
When would I need to convert joule 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).
