Treadmill Pace Chart: MPH, KM/H, Mile and Kilometer Pace
The quick formula: minutes per mile equals 60 ÷ treadmill mph. For metric pace, first convert speed using km/h = mph × 1.609344, then divide 60 by km/h.
The chart below assumes the treadmill holds its displayed speed continuously, with no warm-up, cooldown, pauses, or speed changes. It converts belt speed; it does not guarantee outdoor race performance or prove that a specific treadmill is calibrated correctly.
Treadmill Speed and Pace Chart
Times are rounded to the nearest second. The km/h column is rounded to one decimal for display, but pace calculations use the unrounded conversion.

Projected Race Times at a Constant Treadmill Speed
These are mathematical projections, not predictions. They assume an immediate start at the listed speed and continuous running at that speed for the full distance.
| MPH | 5K | 10K | Half marathon |
|---|---|---|---|
| 4.0 | 46:36 | 1:33:12 | 3:16:38 |
| 5.0 | 37:17 | 1:14:34 | 2:37:19 |

How to Convert a Speed That Is Not in the Chart
MPH to minutes per mile
Divide 60 by speed. At 6.8 mph: 60 ÷ 6.8 = 8.8235 minutes. Keep the 8 minutes, then multiply 0.8235 × 60 = 49 seconds. Pace is approximately 8:49 per mile.
MPH to km/h
Multiply mph by 1.609344. At 6.8 mph: 6.8 × 1.609344 = 10.94 km/h.
KM/H to minutes per kilometer
Divide 60 by km/h. At 10.94 km/h: 60 ÷ 10.94 = 5.48 minutes, or approximately 5:29 per kilometer.
Why Your Watch May Show a Different Pace
- Treadmill calibration: the displayed speed may differ slightly from actual belt speed, especially after belt, roller, motor, or controller changes.
- Watch estimation: indoor pace is often estimated from wrist motion or a foot pod rather than GPS.
- Acceleration: the console may use target speed while the belt is still speeding up or slowing down.
- Workout averages: warm-up, recovery, pauses, and cooldown change the average pace even if the work interval matches the chart.
- Belt interaction: holding the rails, pushing the belt, or running too far forward or backward can change movement without changing the display.
Use one device consistently for training comparisons. If accuracy matters, follow the manufacturer’s calibration procedure or arrange service rather than trying to measure a moving belt by hand.
Does Incline Change the Pace Conversion?
No. A treadmill set to 6.0 mph still moves at a nominal 10:00-per-mile belt speed whether the incline is 0% or 5%. Incline changes effort and mechanics, not the speed-to-pace arithmetic.
There is no single incline setting that makes every treadmill pace equivalent to every outdoor run. Wind, surface, temperature, treadmill calibration, runner mechanics, and the specific workout all matter. Treat incline as a training variable rather than a pace correction formula.
Use the Chart in a Workout
- Choose the target pace, then find the nearest treadmill speed.
- Warm up before reaching the target speed.
- Use small speed changes rather than jumping directly to a fast setting.
- Stand on the side rails while starting the belt and attach the safety clip.
- For intervals, record both the work speed and recovery speed.
- Stop for chest pain, dizziness, unusual shortness of breath, loss of control, or equipment malfunction.
