Converting km to miles is needed constantly for travel distances, race and running route lengths, vehicle mileage figures, and comparing metric distances (used almost everywhere) against the mile-based system still used in the US and UK. This page covers exactly how many miles are in a kilometer, a full conversion chart, and worked examples across commonly searched values. The reverse conversion is at miles to km. For other length units, use the length converter. Browse all converters if you need a different tool.
How Many Miles in a Kilometer?
The Exact Conversion Factor
1 km ≈ 0.621371 miles (based on the exact standard: 1 mile = 1.609344 km)
To convert km to miles, multiply the kilometer value by 0.621371, or equivalently divide by 1.609344. This uses the exact kilometer-to-mile standard (NIST international mile).

How Many Kilometers in a Mile (The Reverse Question)
While this page focuses on converting km to miles, the reverse question — how many kilometers are in a mile — is exactly 1.609344 km, since 1 mile is defined as exactly 1.609344 km. For converting mile figures into km directly, the miles to km converter is built for that specific direction.
Mileage: Converting KM to Miles for Travel and Vehicles
Converting mileage from km to miles is a common need for anyone comparing a vehicle's distance traveled, fuel efficiency figures, or a trip's total distance between metric and mile-based units — the same conversion factor (multiply km by 0.621371) applies regardless of whether the distance is a daily commute, a road trip, or a vehicle's total lifetime mileage.
