Question: how many calories you burn walking 6 km?
Answer: 6km = one hour's average walking for me (I am tall so this wouldn't make me pant) ………….. so between 300 and 400 calories. As a rule of thumb we burn, on average, between 3 calories and 5 calories per hour, for every kilogram of weight. Carrying more weight (a pack etc) adds to the measured weight.
