How the conversion works
Multiply by 0.6213711922 to go from kilometer to mile, or divide by it to go back. Every conversion on this site routes through the SI value (m) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? mile to kilometer: 1 mi = 1.609344 km.
