How to Convert Running Pace to Speed
Runners think in pace (minutes per kilometer or mile), while treadmills and GPS watches often display speed (km/h or mph). Converting between them is straightforward but frequently needed.
Pace to speed formula: Speed = 60 ÷ pace (in minutes per unit). For pace in minutes:seconds, convert seconds to decimal first. Example: 5:30/km pace → 5.5 min/km → 60 ÷ 5.5 = 10.9 km/h.
Speed to pace formula: Pace = 60 ÷ speed. Example: 12 km/h → 60 ÷ 12 = 5:00/km pace.
Common running pace conversions:
| Pace (min/km) | Speed (km/h) | Pace (min/mile) | Speed (mph) |
|---|---|---|---|
| 4:00 | 15.0 | 6:26 | 9.3 |
| 5:00 | 12.0 | 8:03 | 7.5 |
| 6:00 | 10.0 | 9:39 | 6.2 |
| 7:00 | 8.6 | 11:16 | 5.3 |
| 8:00 | 7.5 | 12:52 | 4.7 |
Km to mile pace conversion: Multiply km pace by 1.609 to get mile pace. A 5:00/km pace ≈ 8:03/mile. A 8:00/mile pace ≈ 4:58/km.
Treadmill tip: Most treadmills display speed in km/h or mph. If your training plan uses pace, convert before starting so you know which speed to set.
