§02The Formula

How it’s calculated

1 gigawatt = 1.00000e+12 milliwatts → value_in_milliwatt = value_in_gigawatt × 1.00000e+12

Where

value_in_gigawatt
The number of gigawatts you start with (the value you enter above)
value_in_milliwatt
The equivalent number of milliwatts (the result)
factor
The exact conversion ratio — 1.00000e+12 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 gigawatts to milliwatts.

  1. 01Look up the SI factors: 1 gigawatt = 1000000000 base units, 1 milliwatt = 0.001 base units.
  2. 02Divide to get the conversion ratio: 1000000000 / 0.001 = 1.00000e+12.
  3. 03Multiply by the quantity: 5 × 1.00000e+12 = 5.00000e+12.
  4. 04So 5 gigawatts = 5.00000e+12 milliwatts.
