About Converting Zettawatts to Foot-pounds per second
Zettawatt and Foot-pound per second 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: Zettawatt is 1e+21 watt units, and mechanical power rate.
Formula
foot-pounds per second = zettawatts × 7.375621e+20
This factor comes from each unit's defined relationship to the category's base unit: 1 zettawatt equals 1e+21 base units, and 1 foot-pound per second equals 1.35581794833 base units, so dividing one by the other gives the direct zettawatt-to-foot-pound per second factor of 7.375621e+20.
Simple example
1 ZW × 7.375621e+20 = 7.375621e+20 ft-lb/s
1 zettawatt = 7.375621e+20 foot-pounds per second.
Real-world example
100 ZW × 7.375621e+20 = 7.375621e+22 ft-lb/s
100 zettawatts = 7.375621e+22 foot-pounds per second.
