Miles to Kilometres
A mile is 1.609344 kilometres exactly.
The rows below include the distances people actually convert: race distances, speed limits read as numbers, and the marathon — which is 26.2 miles and 42.195 kilometres, a figure fixed by the 1908 London course rather than by any round number.
A nautical mile is a different unit again, 1.852 kilometres, used at sea and in the air. If your figure came from a chart or a flight plan, that is the one you want.
The formula
kilometres = miles × 1.609344
