The calculation, without hidden assumptions
Running pace is elapsed time per unit distance. MAXScanner can solve any side of the relationship instead of forcing one direction: pace = time/distance, time = pace × distance, or distance = time/pace. Results always show both min/km and min/mile plus average speed, and the split table extends the same arithmetic pace across common race distances.
How to use this calculator
Choose whether to solve pace, finish time or distance.
Select kilometres or miles for distance and enter the known distance when required.
Enter elapsed time as hours, minutes and seconds, or enter target pace as minutes and seconds per km/mile.
Use the split table as constant-pace arithmetic, not as a guarantee that the same effort is sustainable over every distance.
Where people use it
- •Convert a recorded run into min/km, min/mile, km/h and mph
- •Find the pace needed for a target 5K, 10K, half-marathon or marathon finish time
- •Calculate finish time from a chosen training/race pace and distance
- •Estimate distance covered during a timed run at a known average pace
Worked example — 10 km in 50:00
50 minutes over 10 km gives 5:00 min/km. That equals about 8:02.3 min/mile, 12.0 km/h and 7.46 mph. Holding exactly the same arithmetic pace would produce a 25:00 5K and 1:45:29 half marathon.
What the result does not assume
- •Common-distance finish times are constant-pace projections only. They do not model fatigue, hills, weather, fueling, fitness or race-specific endurance.
- •GPS distance and moving-time choices can materially change calculated pace. Use the same timing/distance convention when comparing runs.
- •A training pace is not automatically an appropriate race target. Use your training plan, recent performances and health/safety guidance where relevant.
Frequently asked questions
Can I calculate time from pace instead of pace from time?+
Yes. Choose Finish time, enter distance and target pace, and MAXScanner multiplies pace by distance after normalizing km/mile units.
Can I use miles and still see min/km?+
Yes. Inputs can use miles, kilometres, min/mile or min/km; the result reports both pace systems and both common speed units.
Are the 5K and marathon times predictions?+
They are arithmetic constant-pace projections, not performance forecasts. Real sustainable pace generally changes with distance, terrain, weather and fatigue.
Why can GPS pace differ from race pace?+
GPS distance error, auto-pause, moving-time settings and course measurement can all change the denominator or elapsed time used in the pace calculation.

Keep the result connected to the real job
MAXScanner keeps the formula and assumptions beside the result so you can verify the number before using it in a drawing, estimate, specification, worksheet or document. Where a supplier, manufacturer, drawing or applicable standard owns a requirement, that source remains authoritative.
