Frequently asked questions
What is the source unit in this conversion?
The source unit is the gigawatt (GW). A gigawatt is 1e+09 watt units.
What is the destination unit in this conversion?
The destination unit is the milliwatt (mW). A milliwatt is 0.001 watt units.
How do I convert gigawatts to milliwatts?
Multiply the gigawatt value by 1000000000000 to get milliwatt. For example, 1 GW × 1000000000000 = 1000000000000 mW.
Is the gigawatts to milliwatts conversion exact?
Yes. Both units are defined by fixed numeric relationships to the watt, so the conversion factor used here, 1000000000000, is exact.
Where is this conversion commonly used?
It is used when comparing power ratings expressed in gigawatts against equipment, engines, or specifications rated in milliwatts.
Can I convert milliwatts back to gigawatts?
Yes. Multiply the milliwatt value by 1e-12 to get gigawatt.

About this conversion
This page converts gigawatts (GW) into milliwatts (mW), two units used to describe power, the rate at which energy is transferred or work is done.
A gigawatt is 1e+09 watt units.
A milliwatt is 0.001 watt units.
The formula is mW = GW × 1000000000000, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
