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.
About Watts
The watt (W) is the SI unit of power - 1 J/s - named after James Watt (1736-1819). Familiar power levels: smartphone charging 5-65 W; laptop 15-100 W; microwave 700-1,200 W; electric kettle 2,000-3,000 W; human resting metabolism ~80 W; peak sprint ~2,000 W. The now-obsolete 100 W incandescent bulb is replaced by a 10-15 W LED producing the same light. In AC circuits, reactive power uses the var and apparent power the VA, both derived from watts. 1 W = 1 J/s = 1 kg·m²/s³.
