About Converting Microwatts to Gigawatts
Microwatt and Gigawatt 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: Microwatt is 0.000001 watt units, and gigawatt is 1000000000 watt units.
Formula
gigawatts = microwatts × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 microwatt equals 0.000001 base units, and 1 gigawatt equals 1000000000 base units, so dividing one by the other gives the direct microwatt-to-gigawatt factor of 1e-15.
Simple example
1 uW × 1e-15 = 1e-15 GW
1 microwatt = 1e-15 gigawatts.
Real-world example
100 uW × 1e-15 = 1e-13 GW
100 microwatts = 1e-13 gigawatts.

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