How it works
Calculate running pace (minutes per km/mile) and speed from a distance and time.
Enter a distance, its unit, and the time as minutes and seconds. The calculator reports speed in km/h and mph and pace as minutes:seconds per km and per mile.
Formula
Speed = distance ÷ time; pace = time ÷ distance, expressed per km or mile (1 mile = 1.609344 km).
d- Distance (km or mi)
t- Time (min:sec)
Examples
- 10 km in 50 minutesDistance 10 km · time 50:0012 km/h · pace 5:00 per km · ≈ 8:03 per mile
Frequently asked questions
What is a 'good' pace?
It depends on fitness and distance. The calculator only converts distance and time; it does not judge training level.
Can I enter miles?
Yes — choose miles and the calculator reports mph plus per-mile and per-km pace.
How to read the result
Pace is the linchpin metric for runners: the time to cover one km or mile.
Limitations
Single average pace over the whole distance; it does not model splits or elevation.
Source: Speed = distance/time and pace = time/distance over a fixed distance.
