Min/km to Min/mile Converter
Convert a running pace between minutes per kilometer and minutes per mile.
Training plans mix units. A 5:30 kilometer is not a 5:30 mile. Multiply a min/km pace by 1.609344 to get min/mile. Divide a min/mile pace by 1.609344 to get min/km.

How to use this calculator
- Type the pace and choose the unit you already have. The default, 5:30 per kilometer, converts to 8:51 per mile.
- Switch the unit to minutes per mile if the plan you are reading uses miles. A 9:00 mile becomes 5:36 per kilometer.
- The chart under the formula lists common pairs so you can scan without retyping. It does not include race finish times; those are on the distance pace calculators.
How the calculation works
One mile is 1.609344 kilometers, so it takes 1.609344 times as long as a kilometer at the same speed. A pace of 5:30 is 330 seconds per kilometer. 330 × 1.609344 = 531.1 seconds, which rounds to 8:51 per mile.
The reverse is division. A 10:00 mile is 600 seconds. 600 ÷ 1.609344 = 372.8 seconds, or 6:13 per kilometer.
Rounding to the nearest second is enough for road running. The gap between 5:30 and 5:31 per kilometer is about 1.6 seconds per mile, which matters more in a marathon than in a 5K.
Why the two paces are not interchangeable
Kilometer pace looks “faster” as a number because the distance is shorter. Eight minutes per mile is a solid recreational run. Eight minutes per kilometer is a walk-jog. Reading the wrong unit on a workout can turn an easy day into a hard one.
Race distances make the mismatch obvious. Five kilometers is 3.107 miles, not 5 miles. If you multiply a min/km pace by 5 and call it a mile-race time, you are timing the wrong course.
