Length conversion
Kilometres to Miles (km to mi)
Compare a walking route, road journey or race distance in kilometres with land miles. This does not use nautical miles.
1 km ≈ 0.6214 mi — the calculator keeps the stored factor; this summary may be rounded.
A 5 km walking route
- Starting measurement
- 5 km
- Converted value (rounded if needed)
- 3.1069 mi
The converted distance covers the same route. Estimating how long it takes also needs your speed or pace.

How to convert by hand
Reference relationship (display may be rounded)
1 km = 0.621371192 mi
- Multiply the amount in kilometres by the number of miles per unit.
- Use the calculator for the stored precision; copying a short displayed factor introduces extra rounding.
- Round the result to suit your measurement, after completing the calculation.

About kilometres and miles
Convert each measured dimension separately. A width stays a width and a diagonal stays a diagonal; changing units does not turn a product’s nominal size into a measured size.
Kilometre
Metric (SI)One thousand metres. A kilometre is a distance; kilometres per hour describe speed.
Commonly used for: Journey lengths, walking routes and race distances.
Mile
US / Imperial5,280 international feet, or exactly 1.609344 kilometres. This is a land mile, not a nautical mile.
Commonly used for: US and UK road distances, mileage logs and running routes.
Questions
Does this also convert minutes per kilometre to minutes per mile?
No. Pace is time divided by distance, not a distance alone. Enter kilometres here only when you want the equivalent length in miles.
How do I convert miles back to kilometres?
Enter the value in the miles field above to work backwards, or open the Miles to Kilometres converter. This uses the stored factors rather than dividing by a rounded number copied from the chart.
Why might the chart and calculator show different decimal places?
The chart uses a compact rounded display. The editable calculator can show up to six decimal places and uses the factors or temperature formulas stored in the library. More displayed digits do not make the original measurement more precise.
Precision and source
The calculator uses stored conversion factors and temperature formulas, then rounds the result for display. A short decimal in a chart is not a claim of exactness. For a calculation with several steps, keep as much precision as the original measurement supports and round at the end.
