Convert Calories per Second to Calories per Hour
Convert Calories per Second (cal/s) to Calories per Hour (cal/h) instantly and accurately.
Conversion Formula
cal/h = cal/s × 3600
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 Calories per Hour
One calorie per hour (cal/h) equals exactly 0.001163 W - the rate of transferring one thermochemical calorie (4.1868 J) per hour. A resting adult generates ~70-80 W ≈ 60,000-70,000 cal/h of heat. The unit appears in European and Asian HVAC standards for small-appliance heat loads and in laboratory calorimetry reporting metabolic activity of small organisms. Calorimetric enzyme assays also express catalytic heat in cal/h per unit enzyme. 1 cal/h = 0.001163 W.
