How the Running Pace Calculator works
Total time in seconds is divided by the distance. One mile is exactly 1.609344 kilometers.
Pace = Time ÷ Distance
Speed = Distance ÷ Time
1 mile = 1.609344 km
Step-by-step calculation
- 1Enter distance and time.
- 2Convert time to seconds.
- 3Divide time by distance for pace, and distance by time for speed.
Worked example
