Convert Ton of Refrigeration to Kilocalories per Hour
Convert Ton of Refrigeration (RT) to Kilocalories per Hour (kcal/h) instantly and accurately.
Conversion Formula
kcal/h = RT × 3023.949133
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 Kilocalories per Hour
One kilocalorie per hour (kcal/h) equals exactly 1.163 W. It is the natural unit for human metabolic rate: sedentary adult ~60-70 kcal/h; walking 250-350 kcal/h; vigorous cycling 500-700 kcal/h; competitive rowing ~1,200 kcal/h. Treadmills and exercise bikes display kcal/h directly. Industrial drying and evaporation calcs in older metric systems (especially Asia) used kcal/h for heat duty; 1 Mcal/h = 1.163 kW. 1 kcal/h = 1.163 W.
