FAQ
What is the conversion factor from MW to W?
1 MW equals 1000000 W. To convert, multiply the value in megawatts by 1000000.
How do I convert 1 MW to W?
1 MW = 1.00000e+6 W. For any value, multiply by 1000000.
How do I convert W back to MW?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 W = 1e-6 MW.
When would I need to convert megawatt to watt?
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?
Yes. Both MW and W are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
