How it is calculated
MW = GW × 1,000
Multiply the value in gigawatts by 1,000 to get megawatts.
Example
To convert 25 GW to megawatts: 25 × 1,000 = 25,000 MW.

Questions about this tool
How many megawatts are in one gigawatt?
1 GW = 1,000 MW exactly.
How do I convert gigawatts to megawatts?
Use MW = GW × 1,000. For example, 25 GW = 25,000 MW.
How many gigawatts are in one megawatt?
1 MW = 0.001 GW.
What is the difference between mechanical and metric horsepower?
Mechanical horsepower is about 745.7 watts and is used in the US, while metric horsepower (PS) is 735.5 watts and is used in Europe and Japan. The same engine therefore shows a PS figure about 1.4% higher.
How many kilowatts is one ton of refrigeration?
One ton of refrigeration is 12000 BTU per hour, about 3.517 kW of cooling capacity. That is cooling output, not electricity use; the unit draws less power depending on its efficiency.
