Formula
Formula
MW = GW × 1000
Multiply any value in gigawatts by 1000 to obtain the value in megawatts.
Worked example
Convert 1 GW to MW.
- 01Start with 1 GW.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 MW.
Result1 GW = 1000 MW

FAQ
What is the conversion factor from GW to MW?
1 GW equals 1000 MW. To convert, multiply the value in gigawatts by 1000.
How do I convert 1 GW to MW?
1 GW = 1000 MW. For any value, multiply by 1000.
How do I convert MW back to GW?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 MW = 0.001 GW.
When would I need to convert gigawatt 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).
