How to use this calculator

  • Enter your pace as minutes and seconds.
  • Pick conversion direction.
  • Read converted pace plus speed in both km/h and mph.

About this calculator

A mile is 1.609344 km, so to convert min/km to min/mile, multiply by 1.609344. To go the other way, divide. The calculator shows the result formatted as mm:ss and gives you the equivalent km/h and mph speeds for treadmill use.

Frequently asked

Why is min/mile larger than min/km for the same effort?+
A mile is longer than a kilometer, so each mile takes more time. A 5:00/km pace is about 8:03/mile — the same speed, just measured against a longer unit.
How do I convert pace to speed?+
Speed = 60 / pace-in-min/km gives km/h. So 5:00/km = 60/5 = 12 km/h.
Is 1.609 km close enough for the conversion?+
For casual purposes yes; competitive timing uses 1.609344 km exactly. Modern GPS watches all use the precise value.
Why does my watch sometimes show a different pace than I expect?+
GPS pace fluctuates with each second. Most watches smooth pace over 5-10 seconds; some let you switch to "lap pace" or "average pace" for a steadier reading.
Are min/km the same as 1000m splits?+
Yes — min/km is your time for each km. Track-style "1000m splits" mean exactly the same thing.
