About Converting Zeptowatts to Foot-pounds per second
Zeptowatt 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: Zeptowatt is 1e-21 watt units, and mechanical power rate.
Formula
foot-pounds per second = zeptowatts × 7.375621e-22
This factor comes from each unit's defined relationship to the category's base unit: 1 zeptowatt 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 zeptowatt-to-foot-pound per second factor of 7.375621e-22.
Simple example
1 zW × 7.375621e-22 = 7.375621e-22 ft-lb/s
1 zeptowatt = 7.375621e-22 foot-pounds per second.
Real-world example
100 zW × 7.375621e-22 = 7.375621e-20 ft-lb/s
100 zeptowatts = 7.375621e-20 foot-pounds per second.
