About Megawatt
One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.
About Gigawatt
One gigawatt is one billion watts. Utility generation capacity and grid planning commonly use GW.
How to convert megawatts to gigawatts
1 megawatt is equal to 0.001 gigawatt when both are expressed in watt-equivalents:
1 megaw = (1,000,000 W ÷ 1,000,000,000 W) gw = 0.001 gw
Each megawatt is defined as 1,000,000 W and each gigawatt as 1,000,000,000 W in this tool, so one megaw equals 1,000,000 ÷ 1,000,000,000 gw = 0.001 gw.
Let d(megaw) be the numeric value in Megawatt (megaw), and d(gw) the value in Gigawatt (gw). Then:
d(gw) = d(megaw) × (1,000,000 / 1,000,000,000)
Equivalently, divide by how many megaw fit into one gw (watts per gw divided by watts per megaw):
d(gw) = d(megaw) ÷ 1000
Or: gigawatt = megawatt ÷ 1000
Examples
Example #1: Convert 1 megaw to gigawatt
1 megaw = 1 megaw × (1,000,000/1,000,000,000) gw = 0.001 gw
1 megaw = 1 megaw ÷ 1000 = 0.001 gw
Intermediate watts: 1,000,000 W
Example #2: Convert 10 megaw to gigawatt
10 megaw = 10 megaw × (1,000,000/1,000,000,000) gw = 0.01 gw
10 megaw = 10 megaw ÷ 1000 = 0.01 gw
Intermediate watts: 10,000,000 W
Summary
To convert Megawatt to Gigawatt, multiply the value in megaw by the ratio of watts per megaw divided by watts per gw. Equivalently: value_gw = value_megaw × (1000000 / 1000000000). Numerically, 1 megaw equals 0.001 gw.
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 Megawatt to Gigawatt is 1.000000e-3 (1 megaw = 0.001 gw).
