Pace Calculator
HEALTH CALCULATOR
Convert distance and elapsed time into running or walking pace and average speed.
Pace per kilometer5:00 / km
Pace per mile8:03 / mi
Average speed12 km/h
Average speed7.46 mph
How it works
The calculator converts the distance to both kilometers and miles, divides elapsed time by each distance, and converts the inverse into average speed.
Formula
Pace = elapsed time ÷ distance. Average speed = distance ÷ elapsed hours.
Worked example
Five kilometers in 25 minutes equals 5:00 per kilometer, about 8:03 per mile, and 12 km/h average speed.
Important limits
- The result uses average pace and does not show hills, stops, wind, or split variation.
- GPS-measured distance and race-course distance can differ.
- Use safe training progression and medical guidance when appropriate.
Frequently asked questions
Can I use walking times?
Yes. Any positive distance and duration work.
Why does pace per mile look larger?
A mile is longer than a kilometer, so the time required per mile is greater at the same speed.
