how does treadmill calculate distance
Calculate how far you run by timing your workout and comparing it to the pace you set. A treadmill's speed settings typically range in pace from six- to 12-minute miles. Divide the number of minutes that you ran by the per-mile speed to calculate the total distance that you ran. For instance, if you use the treadmill for 60 minutes at a rate of 12 minutes per mile, divide 60 by 12 for a distance of 5 miles. Wear an external tracking device while running on the treadmill to automatically monitor distance if your treadmill is older or doesn't provide accurate speed or distance information.
