Pace & distance converter
Speed
6.78 mph
How to use it
Enter a value in any field — pace in min/km, pace in min/mile, or speed in km/h — the others update automatically. Handy when your training plan uses different units or you're comparing results with US-based tools.
Formula and source
1 mile = 1.609344 km
pace/mile = pace/km × 1.609344
speed (km/h) = 3600 / pace (sec/km)
Exact definition of the mile (international yard and pound, 1959)
Worked example
5:30/km = 8:51/mile = 10.9 km/h = 6.8 mph.
Limitations
- This is a pure unit conversion — it doesn't account for terrain, altitude or conditions; use the GAP calculator for that.
