About Gigawatt

One gigawatt is one billion watts. Utility generation capacity and grid planning commonly use GW.

About Megawatt

One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.

How to convert gigawatts to megawatts

1 gigawatt is equal to 1000 megawatt when both are expressed in watt-equivalents:

1 gw = (1,000,000,000 W ÷ 1,000,000 W) megaw = 1000 megaw

Each gigawatt is defined as 1,000,000,000 W and each megawatt as 1,000,000 W in this tool, so one gw equals 1,000,000,000 ÷ 1,000,000 megaw = 1000 megaw.

Let d(gw) be the numeric value in Gigawatt (gw), and d(megaw) the value in Megawatt (megaw). Then:

d(megaw) = d(gw) × (1,000,000,000 / 1,000,000)

Equivalently, divide by how many gw fit into one megaw (watts per megaw divided by watts per gw):

d(megaw) = d(gw) ÷ 0.001

Or: megawatt = gigawatt ÷ 0.001

Examples

Example #1: Convert 1 gw to megawatt

1 gw = 1 gw × (1,000,000,000/1,000,000) megaw = 1000 megaw

1 gw = 1 gw ÷ 0.001 = 1000 megaw

Intermediate watts: 1,000,000,000 W

Example #2: Convert 10 gw to megawatt

10 gw = 10 gw × (1,000,000,000/1,000,000) megaw = 10000 megaw

10 gw = 10 gw ÷ 0.001 = 10000 megaw

Intermediate watts: 10,000,000,000 W

Summary

To convert Gigawatt to Megawatt, multiply the value in gw by the ratio of watts per gw divided by watts per megaw. Equivalently: value_megaw = value_gw × (1000000000 / 1000000). Numerically, 1 gw equals 1000 megaw.

Relationship context

Both units are SI / decimal power (watts and prefixes). Conversions use fixed watt factors, so results stay consistent with the definitions in this converter. The factor from Gigawatt to Megawatt is 1.000000e+3 (1 gw = 1000 megaw).
