Distance Converter: Mile KM

Turn miles into kilometers — and back — without doing the math yourself.

Type a number, pick a unit, and every other unit updates at once. Miles, yards, feet, kilometers, meters and nautical miles, all on one screen.

BUILT FOR RUNNERS
Race distances are named in kilometers but training logs are often kept in miles. Tap 5K, 10K, half or full marathon and see it in miles right away — no more looking it up.

WHAT YOU CAN DO
• Convert miles, yards and feet to kilometers and meters, and the other way
• Nautical miles included for sailing and aviation
• One tap for 5K, 10K, half marathon and full marathon
• Save distances you look up often
• Copy every result at once

EXACT BY DEFINITION
One mile is exactly 1.609344 km and one yard is exactly 0.9144 m. These are international agreements, not approximations, so the conversion is exact. A marathon shows as 42.195 km — never rounded to 42.2.

DISTANCE ONLY, ON PURPOSE
Millimeters and centimeters are left out. This app is for distance you travel: a run, a drive, a golf shot, a flight. Fewer units means a screen you can read at a glance.

WORKS ANYWHERE
No account, no sign-up. Everything runs on your device, so it keeps working with no connection.

Useful for running and cycling, road trips, golf, sailing, and any time you deal with two measuring systems at once.
