About Converting Terawatts to Yoctowatts
Terawatt and Yoctowatt 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: Terawatt is 1000000000000 watt units, and yoctowatt is 1e-24 watt units.
Formula
yoctowatts = terawatts × 1e+36
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 yoctowatt equals 1e-24 base units, so dividing one by the other gives the direct terawatt-to-yoctowatt factor of 1e+36.
Simple example
1 TW × 1e+36 = 1e+36 yW
1 terawatt = 1e+36 yoctowatts.
Real-world example
100 TW × 1e+36 = 1e+38 yW
100 terawatts = 1e+38 yoctowatts.
