Minutes per Mile to Minutes per Kilometer Converter (min/mi to min/km)

Pace is the time it takes to cover a fixed distance, the reverse of speed. US running plans, treadmills and race results give it per mile, while GPS watches set to metric, races in most other countries and 5K parkruns use minutes per kilometer. A kilometer is shorter than a mile, so the per-kilometer pace is always the smaller number: divide the mile pace by 1.609344.

The converter and the charts work in decimal minutes, so 8.5 means 8 minutes 30 seconds, not 8:50. To read a decimal result as minutes and seconds, multiply the part after the point by 60: a result of 4.971 means 4 minutes and about 58 seconds per kilometer. Pace to pace is a plain division, with no offset, because both units are minutes per distance; the cycling and running converter turns a pace into a speed in km/h or mph.

How to use this tool

1. Type a value in the Minute per Mile box to see it in minutes per kilometer, or type in the Minute per Kilometer box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Speed converter.

Formula

min/km = min/mi ÷ 1.609344

min/mi = min/km × 1.609344

Both factors come from the converter's own definitions: 1 minute per kilometer = 1.609344 minutes per mile and 1 minute per mile = 0.621371192237 minutes per kilometer (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

8 min/mi ≈ 4.97097 min/km

5 min/km = 8.04672 min/mi

Quick mental estimate

Take 5/8 of the mile pace, the same as subtracting 3/8 of it: 8 min/mi → 8 − 3 = 5 min/km, against an exact 4.97 min/km. The shortcut divides by 1.6 instead of 1.609344, so it gives a pace about 0.6% slow, roughly 2 seconds per kilometer at that speed.

Use the converter or the charts when the exact figure matters.

The two units

Minute per Mile (min/mi): Minutes per mile is the time needed to cover one mile (1609.344 m). An 8 min/mi pace is 7.5 mph. Enter positive decimal minutes (7.5 means 7 min 30 s); a stationary object has no finite pace.

Minute per Kilometer (min/km): Minutes per kilometre is pace: the time taken to cover one kilometre. For positive speed and pace, 5 min/km equals 12 km/h. Enter decimal minutes (5.5 means 5 min 30 s); zero and negative values have no finite positive reciprocal pace.
