Convert Calories per Second to Ton of Refrigeration
Convert Calories per Second (cal/s) to Ton of Refrigeration (RT) instantly and accurately.
Conversion Formula
RT = cal/s × 0.001190496216
About Calories per Second
One calorie per second (cal/s) = exactly 4.1868 W. It bridges thermochemistry and power: bomb calorimeters and reaction calorimeters characterise exothermic events by cal/s during the reaction interval. Food science uses cal/s to model heat transfer into food during frying or roasting. Since 1 kcal/s = 4,186.8 W, kilocalories per second appear in high-intensity industrial dryers and continuous-flow reactor heat duties. 1 cal/s = 4.1868 W.
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.
