About Converting Attowatts to Microwatts
Attowatt 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: Attowatt is 1e-18 watt units, and microwatt is 0.000001 watt units.
Formula
microwatts = attowatts × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 attowatt equals 1e-18 base units, and 1 microwatt equals 0.000001 base units, so dividing one by the other gives the direct attowatt-to-microwatt factor of 1e-12.
Simple example
1 aW × 1e-12 = 1e-12 uW
1 attowatt = 1e-12 microwatts.
Real-world example
100 aW × 1e-12 = 1e-10 uW
100 attowatts = 1e-10 microwatts.
