Miles to kilometers is what you need when an American or British distance has to make sense to the rest of the world. Road trip planning, translating running splits, and comparing car range figures between US and European spec sheets all rely on it.
Flight distances are another case. Airlines in the US list route length in statute miles for frequent-flyer programs, while European booking sites show kilometers. New York to London is about 3,460 miles, or 5,570 km. Pilots plan the same route in nautical miles, roughly 3,000 nm, so three different units can describe one journey.
Runners often meet this conversion at the track. Training plans written in the US prescribe mile repeats, but many tracks outside the US are only marked for 400 m laps. A mile is 4 laps plus 9.34 m, so runners add a short extra distance at the end of each repeat to make it a true mile.
Speed limits around 30 mph are 48.3 km/h.
Hiking trails in US parks are signed in miles; a 12 mile trail is 19.3 km.
To check your answer, the kilometer figure should always be about 60% larger than the mile figure. A trip of 300 miles should come out near 480 km; the exact value is 482.8 km. If your result is smaller than the starting number, you divided instead of multiplying. Rental car contracts abroad sometimes cap daily distance in kilometers, so converting your planned mileage before you sign avoids surprise charges.

Convert 65 miles to kilometers.
Answer: 65 miles = 104.6 km.

65 miles is 104.6 km, about one hour of driving at a US highway limit.
An EV rated for 300 miles of EPA range would show 482.8 km, though European WLTP ratings are measured differently.
Roger Bannister's 1954 mile was 1.609 km, about 9 meters longer than the 1,600 m race used in many schools today.
1.6 is fine for chat, but on 250 miles it gives 400 km instead of 402.3 km.
The metric mile is 1,600 m in US high schools and 1,500 m in international athletics; the real mile is 1,609.344 m.
Speeds and distances at sea use the nautical mile (1.852 km). A statute mile figure will understate the distance.
One statute mile is exactly 1.609344 km, or 5,280 feet.
Origin. The mile comes from the Roman mille passus. The 1593 English statute fixed it at 8 furlongs so it would align with farmland measurement.
Used today. Miles appear on US and UK road signs and odometers, on US weather forecasts for visibility, and in aviation as the nautical mile's land cousin.
A kilometer is 1,000 meters, about 0.621 miles.
Origin. Introduced with the metric system in France in 1795 and adopted worldwide since.
Used today. Kilometers are standard for road distances, speed limits and maps in most countries, as well as for running and cycling events.
26.2 × 1.609344 = 42.165 km. The official marathon is 26.219 miles, which is exactly 42.195 km.
Because it was set at 8 furlongs and a furlong was 660 feet, so 8 × 660 = 5,280.
1,609.344 meters exactly.
Multiply by 1.6, or add 60%: 50 miles + 30 = 80 km. The precise answer is 80.47 km.
Miles for distance and mph for speed. Small location markers along motorways, however, count in kilometers for maintenance crews.
