About Milliwatt
One milliwatt is one thousandth of a watt. Common in RF, fiber optics, and low-power electronics.
About Gigawatt
One gigawatt is one billion watts. Utility generation capacity and grid planning commonly use GW.
How to convert milliwatts to gigawatts
1 milliwatt is equal to 1.00000000e-12 gigawatt when both are expressed in watt-equivalents:
1 mw = (0.001 W ÷ 1,000,000,000 W) gw = 1.00000000e-12 gw
Each milliwatt is defined as 0.001 W and each gigawatt as 1,000,000,000 W in this tool, so one mw equals 0.001 ÷ 1,000,000,000 gw = 1.00000000e-12 gw.
Let d(mw) be the numeric value in Milliwatt (mw), and d(gw) the value in Gigawatt (gw). Then:
d(gw) = d(mw) × (0.001 / 1,000,000,000)
Equivalently, divide by how many mw fit into one gw (watts per gw divided by watts per mw):
d(gw) = d(mw) ÷ 1.00000000e+12
Or: gigawatt = milliwatt ÷ 1.00000000e+12
Examples
Example #1: Convert 1 mw to gigawatt
1 mw = 1 mw × (0.001/1,000,000,000) gw = 0 gw
1 mw = 1 mw ÷ 1.00000000e+12 = 0 gw
Intermediate watts: 0.001 W
Example #2: Convert 10 mw to gigawatt
10 mw = 10 mw × (0.001/1,000,000,000) gw = 0 gw
10 mw = 10 mw ÷ 1.00000000e+12 = 0 gw
Intermediate watts: 0.01 W
Summary
To convert Milliwatt to Gigawatt, multiply the value in mw by the ratio of watts per mw divided by watts per gw. Equivalently: value_gw = value_mw × (0.001 / 1000000000). Numerically, 1 mw equals 1e-12 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 Milliwatt to Gigawatt is 1.000000e-12 (1 mw = 1e-12 gw).
