Convert a treadmill speed setting (km/h or mph) into a running or walking pace (min/km or min/mile) — and convert a target pace back into the speed to set on the display.
Pace and speed are inverses of each other. Divide 60 by your treadmill's speed in km/h to get your pace in minutes per kilometre, or divide 60 by the speed in mph to get minutes per mile. For example, a treadmill set to 10 km/h works out to a pace of 6:00 per kilometre (60 ÷ 10 = 6). To go the other way, divide 60 by your target pace in minutes to get the speed to set.

Every treadmill shows a speed — a number in km/h or mph that tells you how fast the belt is moving. But most runners plan and think in pace, not speed: training plans, race goals and running apps almost always talk about minutes per kilometre or minutes per mile, not "10.5 on the display." That gap makes it hard to translate a training plan straight onto a treadmill without doing the maths yourself first. It gets more confusing again if the plan was written overseas, since many popular training apps and imported US-style programs prescribe pace in minutes per mile or speed in mph, while an Australian treadmill almost always displays km/h. This calculator bridges that gap in both directions — enter a speed to see the matching pace, or enter a target pace to see exactly what to set the treadmill to.
Speed and pace describe the same movement from opposite directions: speed is distance covered per hour, while pace is time taken per unit of distance. Because of that, one is always the mathematical inverse of the other. If you know the speed in km/h, dividing 60 by that number gives you the pace in minutes per kilometre. If you know the pace in minutes per kilometre, dividing 60 by that number gives you back the speed in km/h. Exactly the same relationship holds for mph and minutes per mile. To move between the metric and imperial systems, the calculator uses the standard conversion that 1 mile equals 1.60934 km, so a speed in km/h divided by 1.60934 gives the equivalent in mph, and a pace in minutes per km multiplied by 1.60934 gives the equivalent in minutes per mile.
Common treadmill speed increments in km/h, with the exact pace each one produces, calculated directly from the formula above.
| Speed (km/h) | Pace (min/km) |
|---|---|
| 5.0 km/h | 12:00 /km |
| 6.0 km/h | 10:00 /km |
| 7.0 km/h | 8:34 /km |
| 8.0 km/h | 7:30 /km |
| 9.0 km/h | 6:40 /km |
| 10.0 km/h | 6:00 /km |
| 11.0 km/h | 5:27 /km |
| 12.0 km/h | 5:00 /km |
| 13.0 km/h | 4:37 /km |
| 14.0 km/h | 4:17 /km |
The same conversion in mph, for treadmills or training plans that use imperial units, in 0.5 mph increments.
| Speed (mph) | Pace (min/mile) |
|---|---|
| 3.0 mph | 20:00 /mile |
| 3.5 mph | 17:09 /mile |
| 4.0 mph | 15:00 /mile |
| 4.5 mph | 13:20 /mile |
| 5.0 mph | 12:00 /mile |
| 5.5 mph | 10:55 /mile |
| 6.0 mph | 10:00 /mile |
| 6.5 mph | 9:14 /mile |
| 7.0 mph | 8:34 /mile |
| 7.5 mph | 8:00 /mile |
| 8.0 mph | 7:30 /mile |
| 8.5 mph | 7:04 /mile |
| 9.0 mph | 6:40 /mile |
The numbers this calculator produces are an exact mathematical conversion of the treadmill's belt speed — they are not a prediction of how that pace will feel underfoot. A moving belt assists your leg turnover slightly, and running indoors removes the air resistance you would push against outdoors, so many runners find a given treadmill pace feels a little easier than running the same pace on the road or track. Because of this, treadmill pace and outdoor race pace are not perfectly identical, even though the numbers on the display match. Some runners add a small incline, often around 1%, to make treadmill effort feel closer to outdoor running, though that is a training choice rather than something this speed-to-pace conversion accounts for.
Speed tells you how far you travel in an hour; pace tells you how long a single kilometre or mile takes. Because both describe the same steady movement, converting one into the other only ever requires dividing 60 (the number of minutes in an hour) by whichever figure you already have. There is no rounding trick or approximation involved — it is exact arithmetic, which is why the quick-reference tables above can be calculated to the second rather than estimated.
Many well-known running apps, coaches and training programs are US-published and prescribe workouts in miles — either as a target pace in minutes per mile or a treadmill speed in mph. An Australian treadmill will almost always show km/h instead, because Australia uses the metric system throughout its road signage, weather reports and consumer products. Rather than mentally estimating the conversion mid-session, entering the plan's target pace or speed into the calculator above gives the exact km/h figure to key into the console before you start.
How do I convert treadmill speed to pace?
Divide 60 by the speed in km/h to get your pace in minutes per kilometre (or divide 60 by mph for minutes per mile). For example, a treadmill set to 10 km/h converts to a pace of 6:00 per kilometre (60 ÷ 10 = 6). The calculator above does this instantly for both km/h and mph, and shows the cross-unit equivalent as well.
What treadmill speed gives a 5:00/km pace?
A 5:00 per kilometre pace corresponds to 12 km/h (60 ÷ 5 = 12), which is about 7.46 mph. Enter "5:00" as your target pace in min/km using the "Pace → Speed" option above to confirm the exact treadmill setting for any target pace.
Does treadmill incline affect my effective pace?
Yes. The speed and pace shown on a treadmill only describe how fast the belt is moving, not how hard you are working. Adding incline increases the effort required to hold a given speed, so a treadmill "pace" on an incline generally feels harder than the same pace on the flat, even though the displayed number does not change. This calculator only converts speed to pace and does not attempt to adjust the number for incline.
Why do treadmills in Australia show km/h instead of mph?
Australia uses the metric system, so local treadmills, gyms, and fitness apps almost always display speed in kilometres per hour. Many popular treadmill brands, workout apps, and training plans originating in the US or UK use miles per hour or minutes-per-mile pace instead, which is why a quick converter is useful when following an imported program on an Australian machine.
Is treadmill pace the same as outdoor running pace?
Not exactly. A moving belt assists your leg turnover slightly and there is no air resistance to push through indoors, so many runners find a given treadmill pace feels a little easier than the same pace outdoors. Some runners compensate by adding a small incline (often around 1%) to better approximate outdoor effort, though the treadmill's speed and pace numbers themselves remain a straightforward mathematical conversion regardless of how the effort feels.
How do I convert between mph and km/h on a treadmill?
Multiply a speed in km/h by 0.62137 to get mph, or multiply mph by 1.60934 to get km/h. For example, 10 km/h × 0.62137 ≈ 6.21 mph, and 6 mph × 1.60934 ≈ 9.66 km/h. The calculator above performs this conversion automatically alongside the pace conversion.
What treadmill speed should I use for a 5K training plan?
It depends on your target pace, but you can work it out directly: divide 60 by your target minutes-per-km pace to get the km/h setting. For example, a 5K training plan built around a 6:00/km pace means setting the treadmill to 10 km/h (60 ÷ 6 = 10) for those sessions.
