About Converting Gigawatts to Microwatts
Gigawatt and Microwatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Gigawatt is 1000000000 watt units, and microwatt is 0.000001 watt units.
Formula
microwatts = gigawatts × 1e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 gigawatt equals 1000000000 base units, and 1 microwatt equals 0.000001 base units, so dividing one by the other gives the direct gigawatt-to-microwatt factor of 1e+15.
Simple example
1 GW × 1e+15 = 1e+15 uW
1 gigawatt = 1e+15 microwatts.
Real-world example
100 GW × 1e+15 = 1e+17 uW
100 gigawatts = 1e+17 microwatts.

Reverse conversion: Microwatt to Gigawatt
1e+15 uW × 1e-15 = 1 GW
1e+15 microwatts = 1 gigawatt.
gigawatts = microwatts × 1e-15
