Treadmill Pace Calculator

Convert the number on the treadmill into min/km or min/mile, or enter pace to find the matching belt speed and distance.

How it works

Choose Speed or Pace first, then choose metric or imperial units. Distance is belt speed multiplied by elapsed time; incline does not change belt distance.

Formula

Pace in min/km = 60 ÷ km/h. Pace in min/mile = 60 ÷ mph. Unit conversion uses exactly 1 mile = 1.609344 kilometers.

Source: NIST Guide to the SI conversion factors.

Example

10 km/h equals 6:00 min/km. A 30-minute session at that speed covers 5 km. In imperial units, 6 mph equals 10:00 min/mile.

FAQ

Does incline change pace?

It changes effort, not the belt's distance calculation. Use the incline tool to compare estimated metabolic demand at the same speed.
