Based on an average walking stride. Running lengthens your stride by roughly a third, so the same step count covers more distance when running.
What The Steps To Miles Calculator Works Out
- Miles: steps multiplied by your stride length, converted at 1 km = 0.6214 miles. For someone of average height 10,000 steps is roughly 4.5 to 5 miles.
- Kilometres: the same distance in metric; 10,000 average steps is about 7.4 km.
- Stride used: the UK average of 74 cm unless you enter a height, in which case walking stride is taken as about 41% of height: around 74 cm at 5ft 10in and 66 cm at 5ft 3in. Phone and watch step counters estimate stride the same way and then refine it with motion data, so expect small differences between devices.
- Step table: distances for 1,000 to 20,000 steps at your stride. Health benefits climb steeply up to around 7,000 to 8,000 daily steps and continue more gently beyond; the NHS suggests a brisk 10-minute walk daily as a minimum, roughly 1,000 steps.
- Height entered in (advanced): switch the height box to inches if you think in feet and inches (5ft 9in is 69 inches).
- Activity (advanced): lengthens the stride for brisk walking (+10%), jogging (+33%) or running (+55%), so the same step count covers more ground. It also raises the calorie rate, since running costs roughly 1 kcal per kg per km against about 0.53 kcal for walking.
- Measured stride length (advanced): if you have paced out ten steps and divided the distance by ten, enter the result here and it overrides both the average and the height estimate.
- Calories burned (advanced): distance x bodyweight x the energy cost per km for the activity. A 75 kg adult walking 10,000 steps burns roughly 300 kcal; this is a general estimate, not a measurement.
- Time on your feet (advanced): distance divided by your walking speed. Normal walking is about 5 km/h (3.1 mph) and brisk walking 6 km/h or more, so 10,000 steps take roughly an hour and a half of actual walking.
- Daily goal and weekly totals (advanced): how far through your step target today's count gets you, plus the distance and calories if you repeated it every day for a week. The 10,000-step target began as marketing for a 1960s Japanese pedometer, but research since has broadly supported it as a reasonable goal. For distance-critical training, GPS tracking is more accurate than any step count.
