About KM to Miles Converter

Convert kilometres to miles. A mile is exactly 1.609344 km, so miles = km ÷ 1.609344, or about km × 0.6214. Common distances: 5 km = 3.107 mi, 10 km = 6.214 mi, a half marathon (21.0975 km) = 13.109 mi, a marathon (42.195 km) = 26.219 mi and 100 km = 62.137 mi. The page opens with Kilometre in From and Mile in To, and the table adds metres, feet, yards and nautical miles.

How to Use

Type the kilometres

Enter the distance in the From box, such as 5 for a parkrun or 42.195 for a marathon.

Read the miles

The To box shows miles to up to 10 significant digits, and the sentence below gives both values.
