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

Runners outside the US usually train in minutes per kilometer: a watch beeps at every kilometer, and race splits in Europe, Asia and Australia come at kilometer markers. American plans, treadmills and many coaching books give the same targets per mile. Multiplying a kilometer pace by 1.609344 gives the mile pace, because each mile is that many kilometers long. Treadmills sold in the US usually display mph, so a metric runner on one needs a second step from pace to speed; the cycling and running converter handles it.

Both charts are in decimal minutes, so 5.25 min/km reads as 5:15 per kilometer. Finish times turn into pace easily: a 25-minute 5K is a 5 min/km average, and the table of finish times shows that a sub-90-minute half marathon and a sub-3-hour marathon need the same pace, about 4:16 per kilometer. For a race plan, convert the goal pace once, then check your splits against whichever markers the course actually uses.

How to use this tool

1. Type a value in the Minute per Kilometer box to see it in minutes per mile, or type in the Minute per Mile 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/mi = min/km × 1.609344

min/km = min/mi ÷ 1.609344

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

Example

Two conversions worked with the same factors the converter uses:

5 min/km = 8.04672 min/mi

9 min/mi ≈ 5.59234 min/km

Quick mental estimate

Multiply by 1.6, done as the pace plus 60% of it: 5 min/km → 5 + 3 = 8 min/mi, against an exact 8.05 min/mi. Using 1.6 makes the mile pace about 0.6% too fast, close to 3 seconds per mile at that speed.

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

The two units

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.

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.
