About Converting Yoctowatts to Megawatts
Yoctowatt and Megawatt 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: Yoctowatt is 1e-24 watt units, and megawatt is 1000000 watt units.
Formula
megawatts = yoctowatts × 1e-30
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctowatt equals 1e-24 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct yoctowatt-to-megawatt factor of 1e-30.
Simple example
1 yW × 1e-30 = 1e-30 MW
1 yoctowatt = 1e-30 megawatts.
Real-world example
100 yW × 1e-30 = 1e-28 MW
100 yoctowatts = 1e-28 megawatts.
