How many calories do you consume by walking one hour.
If you are 75 kgs in weight and walk 5 kilometres per hour the calculation (approximate is as follows)
1 joule = 0.1019716213009 kilogram-force meter
1 kcal = 4,187 kJ.
Walking 5 kmph requres 17 Kj
Hence one hour walking results in 17*60 = 1020 kJ/hour
Hence kcal/hour = 1020/4.187 = 243 kcal/hour.
