It depends on how long your steps are.
If you are trying to calibrate your pedometer, you can do it by taking a number of steps, then measuring the distance you covered. Or, you can count the number of steps around a track of known length. Your shoes may make a difference, too. Sometimes folks take shorter steps when wearing heavy shoes or shoes that have some elevation in the heel.
My guess is that there will be somewhere between 1500 and 2700 steps per mile for an adult of normal height wearing good walking shoes.
