How this calculation works
Pace is time per unit distance; a smaller pace number is faster. This tool returns decimal minutes per kilometre, so 6.5 minutes means 6 minutes 30 seconds.
Pace = minutes ÷ kilometres; speed = kilometres ÷ minutes × 60A worked example
5 km completed in 30 minutes gives a pace of 6 min/km and speed of 10 km/h.
Good to know
Uses the stated formula and assumptions. Displayed decimal values are rounded; use consistent units for all inputs.
A smaller pace number means a faster run
Six minutes per kilometre is faster than seven minutes per kilometre because less time is needed to cover the same distance. A speed number works in the opposite direction: 10 km/h is faster than 8 km/h. Pace and speed express reciprocal relationships with different units.
This calculator displays decimal minutes. A pace of 6.5 min/km means six minutes thirty seconds, not six minutes five seconds. Multiply the decimal fraction by 60 to obtain the seconds component.
An average does not describe every segment
A 5 km distance completed in 30 minutes has an average pace of 6 min/km whether each kilometre took six minutes or the runner alternated fast and slow segments. The endpoints determine the average but hide the within-run pattern.
Use elapsed time or moving time consistently when comparing efforts. Stops, terrain and measurement methods can change the interpretation. This arithmetic tool does not set a training intensity or prescribe a target based on health or ability.
A few questions, answered
How do I enter 30 minutes 30 seconds?
Enter 30.5 minutes. Seconds are divided by 60 before being added to whole minutes.
Does this predict a race result?
No. It summarizes the distance and time you enter without modeling future performance.
