About Metric Horsepower
The metric horsepower (PS/CV/pk) equals exactly 75 kgf·m/s = 735.49875 W - the European equivalent of mechanical horsepower, defined as lifting 75 kg by 1 m/s. It was the DIN 66036 standard for European automotive ratings until the EU mandated kW. A 100 PS car produces 73.55 kW; 200 PS = 147.1 kW. The ~1.4% difference from mechanical hp (745.7 W) means a 100 PS car rates as 98.6 mechanical hp. German car advertising still shows PS parenthetically alongside kW. 1 PS = 735.49875 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.
