歩数をマイルに変換する方法
The Steps to Miles Formula
Miles = Steps × Step Length (m) ÷ 1,609.344
To convert steps to miles, multiply your step count by your step length in metres, then divide by 1,609.344 (the number of metres in one mile). For most adults it takes about 2,000–2,400 steps to walk one mile — roughly 2,112 steps for an average man (0.762 m step) and about 2,402 steps for an average woman (0.670 m step). That makes the popular 10,000-step goal roughly 4.73 miles. Enter your own step count in the calculator above — it is set to miles by default — for an instant, personalized distance in miles.
How Many Miles Is 10,000 Steps? Steps to Miles Chart
The chart below shows how far common step counts are in miles for walking, jogging, running and hiking. Because a running stride is much longer than a walking stride, the same number of steps covers more miles when you run. Values use average adult stride lengths; enter your height above for a figure matched to you.

Steps per Mile by Height
Your height sets your stride, and your stride sets how many steps fit in a mile. Taller people clear a mile in fewer steps; shorter people take more. The table shows steps per mile and the distance of a 10,000-step day for men and women across heights.
| Height | Men: steps/mile | Women: steps/mile | Men: 10k steps (mi) | Women: 10k steps (mi) |
|---|---|---|---|---|
| 152 cm (5'0") | 2,550 | 2,563 | 3.92 | 3.90 |
| 157 cm (5'2") | 2,468 | 2,484 | 4.05 | 4.03 |
| 163 cm (5'4") | 2,381 | 2,391 | 4.20 | 4.18 |
| 168 cm (5'6") | 2,309 | 2,319 | 4.33 | 4.31 |
| 173 cm (5'8") | 2,241 | 2,254 | 4.46 | 4.44 |
| 178 cm (5'10") | 2,178 | 2,190 | 4.59 | 4.57 |
| 183 cm (6'0") | 2,120 | 2,129 | 4.72 | 4.70 |
| 188 cm (6'2") | 2,063 | 2,074 | 4.85 | 4.82 |
| 193 cm (6'4") | 2,009 | 2,019 | 4.98 | 4.95 |

Steps per Mile by Activity
Walking, jogging, running and hiking each use a different stride, so the number of steps in a mile changes with your activity. The table compares them for an average adult.
| Activity | Stride factor | Step length (m) | Steps per mile | Miles per 10k steps |
|---|---|---|---|---|
| Walking | 0.415 | 0.762 | 2,112 | 4.73 |
| Jogging | 0.550 | 1.010 | 1,594 | 6.28 |
| Running | 0.650 | 1.193 | 1,348 | 7.42 |
| Hiking | 0.400 | 0.734 | 2,191 | 4.56 |
On uneven trails you take shorter steps, so hiking needs more steps per mile than road walking — see hiking steps to miles. On a machine, treadmill steps to miles matches your tracked steps to the console distance.
How Many Miles Should You Walk a Day?
Framing your daily target in miles makes it concrete. The table converts common step goals to walking miles and the time they take at a steady 3 mph pace.
| Daily goal | Distance (mi) | Walk time | Activity level |
|---|---|---|---|
| 5,000 steps | 2.37 | 46 min | Sedentary / beginner |
| 7,500 steps | 3.55 | 1 h 9 min | Lightly active |
| 10,000 steps | 4.73 | 1 h 31 min | Active |
| 15,000 steps | 7.10 | 2 h 17 min | Very active |
| 20,000 steps | 9.47 | 3 h 3 min | Highly active / athlete |
Calories Burned per Mile
Distance is only half the story: heavier bodies and faster activities burn more energy over the same mile. The table shows the calories burned covering one mile by body weight and activity.
| Body weight | Walking (kcal/mi) | Jogging (kcal/mi) | Running (kcal/mi) |
|---|---|---|---|
| 54 kg (120 lbs) | 61 | 76 | 83 |
| 68 kg (150 lbs) | 77 | 96 | 105 |
| 77 kg (170 lbs) | 87 | 108 | 119 |
| 82 kg (180 lbs) | 92 | 115 | 126 |
| 91 kg (200 lbs) | 103 | 128 | 140 |
How Many Steps in a 5K, 10K, Half & Full Marathon
