Calculate walking pace and speed from distance and elapsed time. See minutes per mile, minutes per kilometer, mph, and km/h, with an optional age-and-sex population reference.
Enter distance and elapsed time. Age and sex are optional and never change the core pace calculation.
Age and sex do not change your calculated pace. They are used only to compare your speed with published short-distance usual-gait means.
Walking pace is a measurement, not a prescription: This calculator measures the pace implied by the distance and elapsed time you enter. It does not determine how fast you should walk. Comfortable and sustainable walking speed varies by person, terrain, health, environment, and purpose.
Enter distance and elapsed time to calculate walking pace (min/mile or min/km) and walking speed (mph or km/h). Pace is time divided by distance; speed is distance divided by time. Optional age and sex selections only add a population-reference comparison, not a different pace calculation.
Age and sex are optional and only affect the population-reference comparison.
1 mile = 1.609344 kilometers
Pace per mile = total seconds ÷ miles
Pace per kilometer = total seconds ÷ kilometers
mph = miles ÷ elapsed hours
km/h = kilometers ÷ elapsed hours
Walking 3 miles in 51 minutes gives the following results from the calculator:
Pace / mile
17:00 min/mi
Pace / km
10:34 min/km
Speed
3.53 mph
Metric speed
5.68 km/h
These are mathematical conversions, not personal targets. Convert speed to pace with min/mile = 60 ÷ mph and min/km = 60 ÷ km/h. Reverse the calculation with mph = 60 ÷ pace in min/mile or km/h = 60 ÷ pace in min/km. Use decimal minutes: 17:30 means 17.5 minutes. The minutes-per-mile column also shows how long one mile takes at each listed speed.
| Speed | Metric speed | Pace / mile | Pace / km |
|---|---|---|---|
| 2.0 mph | 3.2 km/h | 30:00 min/mi | 18:38 min/km |
| 2.5 mph | 4.0 km/h | 24:00 min/mi | 14:55 min/km |
| 3.0 mph | 4.8 km/h | 20:00 min/mi | 12:26 min/km |
| 3.5 mph | 5.6 km/h | 17:09 min/mi | 10:39 min/km |
| 4.0 mph | 6.4 km/h | 15:00 min/mi | 9:19 min/km |
| 4.5 mph | 7.2 km/h | 13:20 min/mi | 8:17 min/km |
Age can affect comfortable or sustainable walking speed, but it does not change the arithmetic for a completed walk.
Sex does not change the pace calculation. It is used only for the optional study-group comparison.
Body weight does not change pace from distance and time. It matters more when estimating energy expenditure.
Hills, incline, surface, weather, carried load, and stops can all affect a sustainable real-world pace.
For energy use, see the Walking Calorie Calculator.
The NIH Toolbox study reported walking-speed reference values from 1,320 U.S. adults aged 18–85, timed over 4 meters from a static start. The table shows age-and-sex group means for usual walking speed, not maximum speed. These short-test values are not personal targets or direct equivalents of sustained outdoor walking pace.
| Age | Male mean | Female mean |
|---|---|---|
| 18–29 | 1.18 m/s | 1.11 m/s |
| 30–39 | 1.21 m/s | 1.15 m/s |
| 40–49 | 1.21 m/s | 1.14 m/s |
| 50–59 | 1.16 m/s | 1.15 m/s |
| 60–69 | 1.16 m/s | 1.05 m/s |
| 70–79 | 1.07 m/s | 0.99 m/s |
| 80–85 | 0.97 m/s | 0.95 m/s |
There is no single pace that is right for everyone. A completed walk can be measured exactly from distance and elapsed time, while a comfortable or sustainable pace varies with the person, terrain, conditions, and purpose. CDC lists brisk walking at about 2.5 mph or faster as one example of moderate-intensity activity.
Divide elapsed time by distance. For example, 51 minutes over 3 miles equals 17:00 minutes per mile. This calculator also converts the same result to minutes per kilometer, mph, and km/h.
Pace is time per unit of distance, such as minutes per mile. Speed is distance per unit of time, such as miles per hour. They describe the same movement from opposite directions.
Divide pace in decimal minutes per mile by 1.609344 to get minutes per kilometer; multiply minutes per kilometer by 1.609344 for the reverse conversion. Convert seconds to a fraction of a minute first: 17:30 means 17.5 minutes, not 17.30. The calculator derives both formats from the same distance and time.
There is no single ideal walking pace for each age. The population table shows average usual walking speed by age and sex from the NIH Toolbox study's short 4-meter test, not recommended outdoor paces. Age does not change the distance-and-time calculation for your completed walk.
Body weight does not change the pace implied by a given distance and elapsed time. Weight is more directly relevant to energy expenditure, so use the Walking Calorie Calculator if calories are your goal.
Sex does not change the pace calculation. It is used only if you choose to compare your speed with the published study-group reference values shown on this page.
CDC lists brisk walking at 2.5 mph or faster as one example of moderate-intensity activity, so 3 mph falls within that example. At 3 mph, your pace is 20:00 minutes per mile and your speed is about 4.83 km/h. Actual intensity varies by person; this is not a personal target or medical threshold.
Treadmill belt calibration, incline, GPS error, terrain, stops, wind, and surface conditions can all change the measured distance or the effort required outdoors.
At a steady 2.5 mph, one mile takes 24 minutes; at 3 mph, 20 minutes; at 3.5 mph, about 17 minutes 9 seconds; and at 4 mph, 15 minutes. These are speed-to-time conversions, not a universal average. Stops, hills, and conditions can increase elapsed time.
