About Converting Foot-pounds per second to Ton of refrigerations
Foot-pound per second and Ton of refrigeration both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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.

Frequently asked questions
How many ton of refrigerations are in 1 foot-pound per second?
1 foot-pound per second equals 0.0003855202 ton of refrigerations, using the exact defined conversion factor rather than an estimate.
How do I convert foot-pound per second to ton of refrigeration?
Multiply the foot-pound per second value by 0.000385520239. The converter above does this instantly to whatever precision you set.
How do I convert ton of refrigeration back to foot-pound per second?
Use the reverse factor: 1 ton of refrigeration equals 2,593.897541 foot-pounds per second. You can also use the swap control in the converter above to flip the direction instantly.
What is a foot-pound per second?
Foot-pound per second (ft-lb/s) is a unit of engineering.
What is a ton of refrigeration?
Ton of refrigeration (TR) is a unit of engineering.
Is the foot-pound per second to ton of refrigeration conversion exact?
Yes. Both foot-pound per second and ton of refrigeration are defined by fixed standards rather than physical artifacts, so the factor of 0.000385520239 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
