Convert Ton of Refrigeration to Foot-Pounds per Second
Convert Ton of Refrigeration (RT) to Foot-Pounds per Second (ft⋅lbf/s) instantly and accurately.
Conversion Formula
ft⋅lbf/s = RT × 2593.897541
About Ton of Refrigeration
One ton of refrigeration (RT) = 12,000 BTU/h ≈ 3,517 W - the cooling rate to freeze 1 short ton (2,000 lb) of water in 24 hours. This follows from water's latent heat: 144 BTU/lb × 2,000 lb ÷ 24 h = 12,000 BTU/h. US residential AC is 1.5-5 tons; a large commercial building 500-2,000 tons; a hyperscale data centre 50,000-100,000 tons. The RT is deeply embedded in North American HVAC catalogs, load calculation software, and contractor pricing. 1 RT = 3,516.85 W.
About Foot-Pounds per Second
One foot-pound per second (ft·lbf/s) ≈ 1.3558 W - the natural power unit in the foot-pound-second (FPS) system. Since 1 mechanical horsepower = exactly 550 ft·lbf/s, the conversion 1 ft·lbf/s = 1/550 hp is exact. Used in FPS structural and fluid dynamics: beam deflection power, pump and turbine output, and ballistic energy-transfer calculations. 19th-century American industry rated waterwheel output in ft·lbf/s before horsepower standardisation. 1 ft·lbf/s = 1.35582 W.
