How this conversion works
Road signs, race distances and fitness apps speak kilometres in most of the world and miles in the US and UK. Type in either box and the other side answers — handy for checking what a European road trip or a 5K/10K finish time really means in your own units.
A quick mental rule: miles are roughly kilometres × 0.62, so 100 km of motorway is about 62 miles. For the exact figures, the table below covers 1 to 100 km.
The exact formula
miles = kilometres ÷ 1.609344
1 mile = 1.609344 km exactly (5,280 feet × 0.3048 m). The reverse is kilometres = miles × 1.609344.
