Quickly convert between kilometers and miles
About this calculator
A quick converter between kilometres and miles for driving, running, and travel planning. Enter a value in either unit and get the other instantly — useful for cross-border road trips, race distances, and understanding American specs.
One kilometre equals 0.621371 miles; one mile equals 1.60934 kilometres. The mental shortcut: miles are about five-eighths of kilometres, so 100 km/h is roughly 62 mph.
Tip: Canada switched to metric in the 1970s, so speed limits are km/h nationwide — American visitors, your 65 mph habits translate to about 105 km/h, right at the typical highway limit.
