It is equivalent for 2000 steps. On the basis that a person of average height has a stride length of about 2.1 to 2.5 feet we can say that approximately 2,000 walking/jogging steps make up a mile. This means that 10,000 steps converts to around 5 miles, with average stride length. If you want the figure for one kilometer (or kilometre with British spelling) then you're looking at about 1,250 walking/jogging steps. Additional information for healthier calculation purposes, take 10 steps (making sure you either run or walk, depending on which stride you want to measure), measure the distance in feet and then divide by 10 to get your average stride length.
There are 5,280 feet in a mile. So, divide 5,280 by your stride length figure to get your number of steps in a mile. If you want the answer in kilometers, divide 3,280 by your stride length figure to get your number of steps in 1 km. And, just think - the next time someone tells you that you're only 1 step away from achieving something, you'll know just how far that is.
