MWtoJ/s

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

Factor1 MW = 1000000 J/s

Converter

MW

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

Result
1.00000e+6J/s

Rendered to 6 significant figures.

Formula

Formula
J/s = MW × 1000000

Multiply any value in megawatts by 1000000 to obtain the value in joules per second.

Worked example

Convert 1 MW to J/s.

  1. 01Start with 1 MW.
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 J/s.
Result1 MW = 1.00000e+6 J/s

FAQ

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