Pace Converter — Mile to km, km/h & mph
Free pace converter for runners. Convert min/km to min/mile, mile pace to km pace, and running speed in km/h or mph for treadmill and track workouts.
This pace converter translates between running pace and speed in both metric and imperial units. Enter any one value — pace per kilometre, pace per mile, speed in km/h, or speed in mph — and the other three fields update to match.
Pace (minutes per kilometre or mile) and speed (kilometres or miles per hour) describe the same effort from different angles. Pace is what most runners use on the road; speed is common on treadmills and in cycling-style displays. The relationship is straightforward: speed equals distance divided by time, so 5:00 per km as km/h corresponds to 12 km/h.
Treadmill workouts are a frequent reason to convert between pace and speed. If your plan calls for 6:00 min/km as treadmill speed but the display shows km/h, this tool gives you the equivalent without mental arithmetic. The same applies when you need 12 km/h expressed as min/km pace from a GPS watch or indoor session.
Conversions assume steady, even pacing. Hills, wind, and stops will change your average speed on a run even when your effort-based pace feels consistent.
Frequently asked questions
- How do I convert mile pace to km pace?
- Enter your per-mile pace and the pace converter shows the equivalent min/km, km/h, and mph. This is useful when your training plan uses miles but your watch or race markers use kilometres.
- What is the difference between pace and speed?
- Pace is time per unit of distance (e.g. 5:00 per km). Speed is distance per hour (e.g. 12 km/h). They describe the same effort — pace is common on the road; speed is common on treadmills.
- How do I set treadmill speed from running pace?
- Enter your target min/km or min/mile pace and read the km/h or mph value for the treadmill display. For example, 5:00 per km equals 12 km/h.
- How accurate are mile-to-km pace conversions?
- Conversions use the standard 1 mile = 1.60934 km factor. Results assume steady, even pacing — hills, wind, and stops will change your average speed on a run even when effort feels consistent.
