Question: how many km to lose 1 pound?
Answer: If one mile is equal to roughly 2,000 steps (100 calories) and 1 pound is equal to 3,500 calories, then to lose one pound per week you would need to achieve a 500 calorie deficit each day. In theory, you would need to add 10,000 steps each day (that's five of miles walking) to lose one pound week.
