Convert Calories per Hour to Kilowatts
Convert Calories per Hour (cal/h) to Kilowatts (kW) instantly and accurately.
Conversion Formula
kW = cal/h × 1.163000000e-6
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 Kilowatts
A kilowatt (kW) is 1,000 W - the everyday unit for home, vehicle, and industrial power. Average US home consumption is ~1.2 kW continuous (~10,500 kWh/year). EV motors range from 30 kW (city cars) to 600+ kW (performance models); a Tesla Model S Performance produces 560 kW (751 hp). Industrial gas turbines on commercial aircraft generate 20,000-100,000 kW. Solar installations are sized in kW-peak. Industrial electric motors span from fractional kW to thousands of kW. 1 kW = 1,000 W = 1.341 hp = 3,412.1 BTU/h.
