Convert Calories per Hour to Kilocalories per Hour
Convert Calories per Hour (cal/h) to Kilocalories per Hour (kcal/h) instantly and accurately.
Conversion Formula
kcal/h = cal/h × 0.001
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.
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.
