Gigawatts to Megawatts

Convert Gigawatt to Megawatt instantly. Quick and accurate power conversion for electrical, mechanical, and HVAC applications.

What is the GW → MW Converter?

This tool converts Gigawatt (GW) to Megawatt (MW) quickly and accurately. Whether you work with motors, appliances, HVAC systems, or engineering specs, it gives you instant, reliable results right in your browser.

Conversion factor: 1 GW = 1,000 MW. Multiply any GW value by 1,000 to get MW.

Understanding the Units

Gigawatt (GW)

One billion watts. Used for national power grids, large power stations, and measuring total electricity demand of regions.

Megawatt (MW)

One million watts. Used for power plants, large industrial facilities, and measuring electricity generation capacity.

Common Applications

Power Grids

Scale national grid and regional demand figures into smaller units.

Power Plants

Express station capacity in megawatts or kilowatts.

Energy Planning

Compare generation capacity across projects and regions.

How to Use

Converting GW to MW takes just a few seconds:

Enter the value

Type your Gigawatt value into the first input field.

Read the result

The Megawatt result appears instantly in the second field as you type.

Copy or swap

Use the copy button to grab the result, or the swap button (↔) to reverse the direction and convert MW back to GW.

Conversion Formula

Formula: MW = GW × 1,000. To reverse: GW = MW × 0.001.

Worked Example

For example, 1 GW × 1,000 = 1,000 MW.
