THE BIG PICTURE
Total calories include the energy you would use at rest during this time.
An estimate, not a measurement. See the method and limits below.
UNDERSTAND YOUR SESSION
Read your treadmill setting in pace units
A belt setting and a pace answer different questions about the same movement: how much distance fits into an hour, and how many minutes fit into one distance unit. To convert mph to minutes per mile, divide 60 by the mph entry. The same operation converts km/h to min/km. For example, selecting 4 mph produces 15:00 per mile, while 8 km/h produces 7:30 per kilometre.
The pace input accepts decimal minutes. If your target is 9 minutes 45 seconds per mile, enter 9.75: the 45 seconds contribute three quarters of a minute. The result card writes that value as 9:45, so you can check it against the format used in a running plan.
The distance and 5K figures use one fixed speed throughout. A 20-minute session at 4 mph gives 1.33 miles because it occupies one third of an hour. The 5K figure answers a separate question: how long would five kilometres take at that belt setting? Neither figure adds warm-up transitions, stops, or acceleration time.
Incline changes the effort of a session, but it does not change this speed-to-pace conversion. An outdoor-equivalent pace would require extra assumptions about terrain, air resistance, and the runner. This tool does not disguise those assumptions as a precise conversion.
THE METHOD
A transparent calculation.
Pace (min per distance unit) = 60 ÷ speed
Distance = speed × minutes ÷ 60
5K time (minutes) = 5 ÷ speed in km/h × 60
Read the assumptions.
The estimate uses constant belt speed and your entered duration. Pauses and changing settings need separate calculation. Step length, when used, is your supplied average rather than a measured value.
A FEW GOOD QUESTIONS
Treadmill pace calculator questions
What treadmill speed is a 10-minute mile?
A 10-minute mile is 6 mph, or approximately 9.66 km/h.
What is the difference between min/mile and min/km?
They measure time over different distances. A mile is 1.609344 kilometres, so the numbers cannot be compared without converting the distance unit.
Does a 1% incline change my pace?
The calculation has no grade term. Raising the deck to 1% may change the effort you feel, but a fixed speed entry still produces the same minutes-per-distance result.
Treadmill speed and pace conversion chart
Use this treadmill pace chart to compare belt settings with minutes per mile and kilometre. To convert mph to min per mile, divide 60 by mph; for km/h to min per km, divide 60 by km/h. Converting treadmill mph to km/h uses 1.609344 as the multiplier. The pace-to-treadmill-speed input accepts decimal minutes, so 8:30 is entered as 8.5.
| mph | km/h | min/mile | min/km |
|---|---|---|---|
| 3 | 4.83 | 20:00 | 12:26 |
| 4 | 6.44 | 15:00 | 9:19 |
| 5 | 8.05 | 12:00 | 7:27 |
| 6 | 9.66 | 10:00 | 6:13 |
| 7.5 | 12.07 | 8:00 | 4:58 |
| 8 | 12.87 | 7:30 | 4:40 |
5K and 10K treadmill speed targets
A 30-minute 5K treadmill speed is 10 km/h, approximately 6.21 mph. A 60-minute 10K uses the same speed because distance and time both double. For a different goal, speed in km/h = distance in kilometres × 60 ÷ goal minutes. These are steady-speed conversions; include slower warm-up or walking time separately.
| Target | Required km/h | Required mph |
|---|---|---|
| 5K in 25 minutes | 12.00 | 7.46 |
| 5K in 30 minutes | 10.00 | 6.21 |
| 10K in 50 minutes | 12.00 | 7.46 |
| 10K in 60 minutes | 10.00 | 6.21 |
The treadmill speed for a 10-minute mile is 6 mph; an 8-minute mile is 7.5 mph. The calculator displays a 5K time at the selected speed; use the formula above for 10K goal speed. Incline-adjusted or outdoor-equivalent pace is a different model and is not supplied by this direct treadmill pace conversion.
