So walking up 100 flights of stairs would burn 50 calories. Of course the process isn't 100% efficient so you would actually burn more than that. W pe 49.99dcal = Dividing by 1000 yields dietetic calories: W pe 4.997 10 4 × cal = W pe 209.2 kJ 1 cal 4.184 J = The person would burn up at least that much energy. Converting to calories, yields: W pe 2.092 10
