How far is 10,000 steps?
About 4¼ miles, or roughly 7 kilometres, for most adults. It depends on the length of your step: 3.8 miles at a 2-foot step, 4.7 miles at 2½ feet. Your iPhone has already measured yours, under Health, Browse, Mobility, Walking Step Length.
The 10,000 figure is not medical advice — it began as a 1965 Japanese pedometer marketing slogan, the manpo-kei, literally “10,000-step meter”. Later research found most of the mortality benefit arrives well before it, which is worth knowing before treating it as a target you failed.
What the number is genuinely good for is scale. Four miles a day is a distance, and distances are comparable to things — which is where it stops being a step count and starts being a fact about your week.
