Gigawatt (GW) to Milliwatt (mW) Conversion

Gigawatt to Milliwatt conversion explained with exact factors, step-by-step examples, and situations where this conversion is commonly used.

Conversion Formula

Milliwatt = Gigawatt × 1.000000e+12

To convert Gigawatt (GW) to Milliwatt (mW), multiply the value by 1.000000e+12. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 GW to mW.

  • Step 1: Write the formula: mW = GW × 1.000000e+12
  • Step 2: Substitute: 1 × 1.000000e+12
  • Step 3: Result: 1.000000e+12 mW
So, 1 GW = 1.000000e+12 mW.
