About Converting Foot-pounds per second to Rontowatts
Foot-pound per second and Rontowatt 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: Mechanical power rate, and rontowatt is 1e-27 watt units.
Formula
rontowatts = foot-pounds per second × 1.355818e+27
This factor comes from each unit's defined relationship to the category's base unit: 1 foot-pound per second equals 1.35581794833 base units, and 1 rontowatt equals 1e-27 base units, so dividing one by the other gives the direct foot-pound per second-to-rontowatt factor of 1.355818e+27.
Simple example
1 ft-lb/s × 1.355818e+27 = 1.355818e+27 rW
1 foot-pound per second = 1.355818e+27 rontowatts.
Real-world example
100 ft-lb/s × 1.355818e+27 = 1.355818e+29 rW
100 foot-pounds per second = 1.355818e+29 rontowatts.
