About this conversion
Kilometers and miles are both units of distance for everyday use, but they belong to different measurement traditions. The kilometer is the global standard; the mile remains the norm in the United States and, on roads, in the United Kingdom. This means that anyone traveling between these two worlds — literally or just consuming media — needs to switch between the two regularly. The conversion factor is approximately 1.609 km per mile (or 0.621 miles per km). The marathon, one of the most universally recognized running distances, is 42.195 km or 26.219 miles. Speed limits offer another everyday comparison: a US highway limit of 65 mph equals about 104.6 km/h. The mile traces its roots to the Roman unit mille passuum (thousand paces), approximately 1,480 meters. Over centuries, it evolved into the current statute mile of exactly 1,609.344 meters, formalized in 1959.
