How it works
Miles-to-kilometers matters for two big audiences: runners translating between US race distances and the metric world (a marathon is 26.2 miles = 42.2 km; a half is 13.1 miles = 21.1 km; a 5K is 3.1 miles), and drivers abroad reading speed limits — 60 mph is 96.6 km/h, so a 100 km/h motorway limit is about 62 mph. One mile is exactly 1.609344 km.
Fibonacci numbers make a surprisingly good shortcut: consecutive Fibonacci values (5, 8, 13, 21…) approximate the ratio, so 5 miles ≈ 8 km and 13 miles ≈ 21 km — the golden ratio (1.618) is close to the true factor (1.609).
1 mi = 1.6093 km — multiply your miles value by 1.6093. For example, 5 Miles (mi) = 8.0467 Kilometers (km). The factor is exact by definition, so results are as precise as your input.
