Switch between the four numbers runners actually use: minutes per kilometre, minutes per mile, km/h, and mph. Enter any one and the other three update instantly, with pace formatted as clean minutes:seconds. It is ideal for matching a treadmill speed to an outdoor pace or comparing race plans across units.
How it works
Pace and speed are inverses of each other, linked by the mile-to-kilometre factor 1 mile = 1.609344 km. From any input the converter computes:
- min/km → km/h: 60 ÷ pace
- km/h → mph: km/h ÷ 1.609344
- min/km → min/mile: pace × 1.609344
- and back the other way for any starting unit
Pace values are shown as minutes:seconds for readability, and speeds as decimals.
Example
Enter a pace of 5:00 min/km:
- min/mile = 5:00 × 1.609344 ≈ 8:02 per mile
- km/h = 60 ÷ 5 = 12 km/h
- mph = 12 ÷ 1.609344 ≈ 7.46 mph
| min/km | min/mile | km/h | mph |
|---|---|---|---|
| 4:00 | 6:26 | 15.0 | 9.32 |
| 5:00 | 8:02 | 12.0 | 7.46 |
| 6:00 | 9:39 | 10.0 | 6.21 |
