How to use Pace & Speed Converter
- Choose min/km, min/mile, km/h or mph. Enter decimal minutes: 5 minutes 30 seconds is 5.5.
- Set your distance in kilometres if you want an estimated completion time. The default is 5 km.
- Compare pace and speed cards and read the time estimate. Change inputs to explore another scenario.
Worked example
5 min/km × 5 km = 25 minutes. Speed = 60 ÷ 5 = 12 km/h.
Method, accuracy & limitations
Speed = 60 / min/km; 1 mile = 1.609344 km.
Exact unit arithmetic with rounding. Time is a constant-pace estimate, not a performance forecast.
Canonical pace must be 1–60 decimal min/km; distance 0.1–1000 km.
Read the unit reference at NIST ↗Frequently asked questions
How do I enter minutes and seconds?
Use minutes + seconds ÷ 60. For 5 minutes 30 seconds, enter 5.5, not 5.30. You can ask HealthWavy AI to help interpret your pace.
What does the time estimate assume?
Time is distance multiplied by pace. It assumes a constant pace without stops, hills or changes in effort; it is not a performance forecast.
Which inputs are accepted?
Pace must convert to between 1 and 60 decimal min/km. Distance must be from 0.1 to 1000 km. Zero and negative inputs are not valid.
How accurate are the units?
One mile is exactly 1.609344 km. Speed in km/h is 60 divided by min/km. Display values are rounded; your measured pace may vary.
