This depends on how much you weigh and how fast you walk.
4246 steps = 2.17 miles
I would recommend finding a "calories burned walking calculator" and plug in 2.17 miles, your weight, and how fast you walked.
Any answer you get will be wrong because it all depends on your metabolic rate, which is how fast you burn fat in your body which differs for every person so you cannot say.
The calories burned when walking depends on your weight and how fast you are walking, so it would be almost impossible to estimate the calories (or partial calories) burned in only one step. The calories burned when walking are usually stated in the distance you walk. For example, a rule of thumb is 100 calories per mile are burned for a 180-pound person and 65 calories per mile for a 120-pound person.
It depends on such things as your body weight, your degree of fitness, and what you are walking on - soft ground, hard ground, flat ground or incline.
The exact amount of calories you will burn walking 10,000 steps will vary depending on a number of factors, these would be: -Your weight 230 -Height -Age -The terrain you are walking on. (flat, hills,etc) -Your walking stride -Your pace But, the average calories burned is between 300-400 calories.
2Another Q&A on this site says:Calories burned walking down 24 flights of stairs? 240That answer means 10 cal walking down 1 flight, which is 5 times this one. And both assume that we know how many steps and/or feet in a "flight", which is by no means standard!
For me - each step of mine is equal to one meter (the start of the feet of 1 leg which is forward to the end of the feet for the other leg which is backward) - there for 8000 steps is equal to 5 miles. Hope this helps
20 STAIR steps (up OR down) will burn ONE calorie.
