About Converting Foot-pounds per second to Ton of refrigerations
Foot-pound per second and Ton of refrigeration 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 cooling power equal to 12,000 BTU/h.
Formula
ton of refrigerations = foot-pounds per second × 0.000385520239037
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 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct foot-pound per second-to-ton of refrigeration factor of 0.000385520239037.
Simple example
1 ft-lb/s × 0.000385520239 = 0.0003855202 TR
1 foot-pound per second = 0.0003855202 ton of refrigerations.
Real-world example
100 ft-lb/s × 0.000385520239 = 0.0385520239 TR
100 foot-pounds per second = 0.0385520239 ton of refrigerations.
