Megawatt [MW] to Gigawatt [GW] Converter

Quick Reference

1 Megawatt (MW) = 0.001 Gigawatt (GW)

1 Gigawatt (GW) = 1000 Megawatt (MW)

How to Convert Megawatt to Gigawatt

1 MW = 0.001 GW
1 GW = 1000 MW

To convert Megawatt to Gigawatt, divide the value by 1000 (equivalently, multiply by 0.001). To convert Gigawatt back to Megawatt, multiply by 1000.

Example: convert 10 MW to GW:
10 MW = 10 x 0.001 = 0.01 GW

↔ Convert Gigawatt to Megawatt

Megawatt

Definition: A megawatt (MW) is a unit of power equal to one million (10⁶) watts. It is a multiple of the base unit, the watt, in the International System of Units (SI).

History/origin: The watt is named in honor of Scottish inventor James Watt. The megawatt, as a decimal multiple of the watt, was derived as a larger unit for measuring very large amounts of power.

Current use: Megawatts are used to measure the power output of power plants, large industrial facilities, and the power consumption of cities. It is a convenient unit for expressing the scale of power generation and consumption on a large scale.

Gigawatt

Definition: A gigawatt (GW) is a unit of power equal to one billion (10⁹) watts. It is a multiple of the base unit, the watt, in the International System of Units (SI).

History/origin: The watt is named in honor of Scottish inventor James Watt. The gigawatt, as a decimal multiple of the watt, was derived as a very large unit for measuring the power output of massive systems.

Current use: Gigawatts are used to measure the total power generation capacity of countries, very large power plants (like nuclear or hydroelectric), and global energy consumption trends. It's used for expressing power on a very large, macroscopic scale.

Megawatt [MW] to Gigawatt [GW] Converter

What is 1 MW in GW?
1 Megawatt (MW) equals 0.001 GW, and 1 GW equals 1,000 MW.
How do I convert Megawatt to Gigawatt?
Divide by 1,000: 10 MW ÷ 1,000 = 0.01 GW. The converter above does it for any value, with the precision you choose.
What is 100 MW in GW?
100 MW = 0.1 GW. Common amounts are listed on this page, each with its own step-by-step page.
Is a Megawatt bigger than a Gigawatt?
No. 1 MW is only 0.001 GW: it takes 1,000 MW to make 1 GW.
