Miles to Kilometers
A mile is 1,609.344 meters, the statute mile used on US and UK road signs and speed limits. A kilometer is 1,000 meters, the standard unit for road distances and speed limits outside the US and UK. 1 mi equals ≈1.60934 km, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to length, measured here against length's base unit (m) — every other length unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
km = mi × ≈1.60934
mi = km × ≈0.621371
Worked example: 5 mi × ≈1.60934 = 8.04672 km.
