Convert Calories per Hour to Megawatts
Convert Calories per Hour (cal/h) to Megawatts (MW) instantly and accurately.
Conversion Formula
MW = cal/h × 1.163000000e-9
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 Megawatts
A megawatt (MW) is 10⁶ W - the standard unit for utility power plant output. A coal unit produces 300-900 MW; a large nuclear reactor 1,000-1,600 MW. Offshore wind turbines reach 15 MW each (Vestas V236-15.0). The Three Gorges Dam totals 22,500 MW. Aluminium smelters consume 500-600 MW; electric arc furnaces 100-300 MW. Solar farms are rated in MWp; pharmaceutical clean-room HVAC systems in MW. 1 MW = 10⁶ W = 1,341 mechanical hp.
