How to convert kilometer to mile
Kilometer (km) and Mile (mi) both measure length. Whether you are studying, traveling, cooking, or working on a project, converting between them should be fast and accurate.
This page converts kilometer to mile — the direction you need when a product, map, or recipe uses metric but you think in US or UK customary units.
The standard relationship used on this page means that 1 kilometer equals 0.621371 mi. Enter any number in the calculator — use the swap button to reverse the direction without leaving the page.
Converting 5 km gives 3.106855 mi. This is a practical reference when switching between kilometer and mile for travel distances, screen sizes, furniture dimensions, and construction plans.

When you'll use this
- Reading distance signs or a rental car GPS in km while thinking in miles as a US or UK driver
- Converting a marathon or race distance (a marathon is 42.195 km) into the familiar 26.2-mile figure
- Understanding a European bike computer or fitness tracker that logs distance in kilometers
- Estimating a flight or road-trip distance quoted in km on an international itinerary
- Comparing a car's European fuel-economy test distance to a US mileage-based commute
Practical note
This page is used constantly by runners and travelers. A half marathon is officially 21.0975 km, which this converter shows as roughly 13.1 miles — the number every US runner recognizes from race bibs and training plans. Road-trippers use it the same way: a European GPS showing "480 km to destination" converts to about 298 miles, letting a US driver estimate drive time using the mph-based speeds they are used to. Because kilometers are the global standard outside the US, UK, and a few other countries, this conversion is one of the most frequently needed length conversions for anyone traveling, training for an international race, or reading foreign news coverage of distances.
Tips
- A quick mental shortcut: multiply km by 0.62 (or divide by 1.6) for a fast estimate before checking the exact figure here.
- European speed limits and trip odometers are almost always in km, so this page pairs naturally with the km/h-to-mph speed converter for planning a driving trip.
- Race distances are a common trap: a "10K" is 10 kilometers (6.2 miles), not 10 miles — don't assume the number matches your home unit.
