How to Convert Ton of Refrigeration to Foot-pound per Second
- 1 TR = 2593.897541 ft·lbf/s
- 1 ft·lbf/s = 0.000385520239 TR
- Example: convert 15 TR to ft·lbf/s: 15 TR = 15 × 2593.897541 ft·lbf/s = 38908.46311 ft·lbf/s
Formula
ft·lbf/s = TR × 2593.897540887
Derivation from SI units:
- 1 TR = 12 000 BTU/h = 3516.8528420667 W
- 1 ft·lbf/s = 1.3558179483314 W
- 1 TR = 3516.852842067 W ÷ 1.355817948331 W per ft·lbf/s = 2593.897540887 ft·lbf/s
Both units are defined exactly, so the factor is exact. Ton of Refrigeration definition: ton of refrigeration; Foot-pound per Second definition: foot-pound per second.
Worked examples
- A reading of 2.5 TR converts to 6484.743852 ft·lbf/s.
2.5 TR × 2593.897541 = 6484.743852 ft·lbf/s - A value of 10 TR is 25938.97541 ft·lbf/s.
10 TR × 2593.897541 = 25938.97541 ft·lbf/s
