1 mile is equal to 1.609344 kilometers.
The distance in kilometers is calculated by multiplying the distance in miles by 1.609344.
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards.
The statute mile of 5,280 feet originated in the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet.
A Roman pace equaled 5 Roman feet, measured from the point at which the heel of one foot was raised to the point at which it was set down again after an intervening step by the other foot.
