MPH to Min/mile Calculator

Treadmills and speedometers report speed (miles per hour or kilometres per hour), while runners think in pace (minutes per mile or per km). This converter translates between the two so you can set the treadmill to the exact speed that matches your goal pace — or work out how fast that 6.5 mph setting really is.

Speed and Pace Are Inverses

Pace is the reciprocal of speed scaled by the time unit. Since there are 60 minutes in an hour:

For example, 6.0 mph gives 60 ÷ 6 = 10 minutes per mile. To express it per km, convert the speed first: 6.0 mph = 9.656 km/h, and 60 ÷ 9.656 ≈ 6:13 per km.

Why the Numbers Feel Counterintuitive

As speed goes up, pace goes down — they move in opposite directions. A small increase in mph at the fast end of the dial shaves more seconds off your mile pace than the same increase at the slow end, because pace is a curve, not a straight line. That is why running 9 to 10 mph drops your mile pace by 40 seconds, while 5 to 6 mph drops it by a full 2 minutes.

Matching Indoor to Outdoor Effort

A treadmill belt has no air resistance, so many runners add a 1–2% incline to make a given speed feel like running the same pace outdoors. If you are training for an outdoor race, set the belt to your goal speed from this converter and add a slight incline to better match real-world effort.

Note: This is a unit conversion. Treadmill calibration can drift, so the displayed speed may differ slightly from reality. The tool is informational and not a substitute for professional coaching or medical advice.
