Use decimal minutes: 50 minutes 30 seconds is 50.5. This describes a run, not a predicted race result.

How to use Running Pace Calculator
- Enter distance, distance unit, finish time (decimal minutes).
- Calculate and compare the labelled result views. Check that every input uses the displayed unit.
- Read the worked example and limits before applying the answer.
Worked example
10 km in 50 minutes = 5:00 per km and 12 km/h.
Formula, accuracy & limitations
Pace = time ÷ distance. Speed = distance ÷ hours.
Use decimal minutes: 50 minutes 30 seconds is 50.5. This describes a run, not a predicted race result.
Calculations use your inputs. Main numeric values show up to six decimal places, percentages up to two, and chart labels up to four. Time results use hours, minutes and seconds. Very small nonzero values use scientific notation.
Read the measurement reference ↗Use distance and elapsed time from the same run
Choose kilometres or miles and enter finish time in decimal minutes. A value of 50.5 is 50 minutes 30 seconds. The mile input is converted using exactly 1.609344 kilometres per mile before calculating minutes per kilometre. This page derives pace from distance and time; the older Pace Converter converts an already known pace or speed.
Read a measured average, not a race forecast
The main result is average pace per kilometre, with speed and mile-pace equivalents. The line shows the elapsed-time relationship if this average pace were constant throughout the supplied distance. Hills, pauses and changing pace are not reconstructed from two numbers.
Frequently asked questions
How do I enter minutes and seconds?
Use minutes plus seconds divided by 60. For 45 minutes 15 seconds, enter 45.25.
Does this give a future finish-time prediction?
It summarizes the run you entered. The straight line is a constant-average illustration, not a forecast of another event.
Can I use elapsed time when I stopped during the run?
Yes, but the answer then includes those stops. For moving pace, supply moving time instead. Use the same time definition when comparing runs.
Why does a smaller pace number mean a faster run?
Pace measures minutes needed per kilometre. Covering a kilometre in 5 minutes is faster than covering it in 6 minutes; speed reverses that relationship.
