Take the quizTreadmill speed vs. outdoor pace
Treadmills display speed in mph or km/h, while most runners think in pace per mile or kilometer. This converter switches between the two instantly in either direction.
Treadmill running and outdoor running at the "same" pace don't always feel identical — the lack of wind resistance and a moving belt versus pushing off stationary ground both change the effort slightly, which is why some runners set a 1% incline to approximate outdoor effort.
Where these numbers come from
The formulas and default values in this calculator are based on:
- Standard mph-to-pace conversion (60 minutes / speed in mph = minutes per mile)
- mile-to-kilometer conversion factor (1.60934)
These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.
Frequently asked questions
Why does treadmill running feel easier than outdoor running at the same pace?
The moving belt assists your stride slightly and there's no wind resistance, which is why many runners set a 1% incline to better simulate outdoor effort.
How do I convert mph to minutes per mile?
Divide 60 by your speed in mph. At 6 mph, that's 60 / 6 = 10 minutes per mile.
Do treadmill calorie counters match outdoor running?
Not exactly — check the calories burned calculator for a separate estimate based on your weight and pace rather than relying solely on the treadmill display.
