Enter any value in kilometers and instantly read the result in miles. The converter comes in handy when you want to compare your running distance with results given in miles, get ready for a trip to the US or UK, or convert speed from km/h to miles per hour. Further down the page you will find ready-made tables for selected popular distances and speeds.
The kilometer is the basic unit of distance in most countries. The mile is used mainly in the United States and the United Kingdom, so converting kilometers to miles is useful above all when you want someone from those countries to understand a distance — or when you compare your own running result with records and training plans given in miles.
One kilometer is about 0.621371 miles. The relationship is fixed, so every conversion comes down to a single multiplication or division. The converter does it for you the moment you type a value, including running distances such as 42.2 km, the length of a marathon.
Below you will find a conversion table for popular distances and a separate table for speed, so you can read how many miles per hour a speedometer reading in km/h corresponds to.
Converting kilometers to miles relies on one fixed relationship: one land mile is exactly 1.609344 kilometers. To turn kilometers into miles, divide the number of kilometers by 1.609344 (the same as multiplying by 0.621371).
The full formula: miles = kilometers ÷ 1.609344. The other way around: kilometers = miles × 1.609344.
Example: you want to know how many miles 100 kilometers is. Plug it in: 100 ÷ 1.609344 = 62.14 miles. In practice it is often enough to multiply the kilometers by 0.62 to get an approximate result.
Another example: a marathon is 42.195 km long, which converts to 42.195 ÷ 1.609344 = 26.22 miles, the 26.2 miles familiar to runners. The converter handles both directions the moment you type a value.

When you drive abroad or read a spec for a car from the American market, converting speed from km/h to miles per hour comes in handy. The factor is the same as for distance — you divide by 1.609344. Values are rounded to two decimal places.
| Kilometers per hour | Miles per hour |
|---|---|
| 30 km/h | 18.64 mph |
| 50 km/h | 31.07 mph |
| 60 km/h | 37.28 mph |
| 70 km/h | 43.50 mph |
| Kilometers per hour | Miles per hour |
|---|---|
| 80 km/h | 49.71 mph |
| 90 km/h | 55.92 mph |
| 100 km/h | 62.14 mph |
| 110 km/h | 68.35 mph |
| Kilometers per hour | Miles per hour |
|---|---|
| 120 km/h | 74.56 mph |
| 130 km/h | 80.78 mph |
Converting kilometers to miles is useful mainly through contact with English-speaking countries. Each of the situations below has its own specifics.
100 km is 62.14 miles. Calculation: 100 ÷ 1.609344 = 62.14 miles. As a rough figure, 100 km is about 62 miles.
50 km is 31.07 miles. Calculation: 50 ÷ 1.609344 = 31.07 miles.
5 km is 3.11 miles. Calculation: 5 ÷ 1.609344 = 3.11 miles. A popular 5 km run therefore comes to a little over 3 miles.
10 km is 6.21 miles. Calculation: 10 ÷ 1.609344 = 6.21 miles.
A marathon is 26.22 miles, the 26.2 miles familiar to runners. Calculation: 42.195 ÷ 1.609344 = 26.22 miles.
A half marathon is 13.11 miles. Calculation: 21.0975 ÷ 1.609344 = 13.11 miles. It is exactly half the marathon distance.
100 km/h is about 62.14 mph. Calculation: 100 ÷ 1.609344 = 62.14 mph. The speed conversion factor is the same as for distance.
Not quite. 1 km is 0.62 miles, a little more than half a mile. Exactly half a mile is 0.805 km, so a kilometer is longer than that.
A mile is bigger. One mile is 1.609344 km, so it is more than 60% longer than a kilometer. That is why the same distance in miles always gives a smaller number than in kilometers.
500 km is 310.69 miles. Calculation: 500 ÷ 1.609344 = 310.69 miles.
35 km is 21.75 miles. Calculation: 35 ÷ 1.609344 = 21.75 miles.
The formula is: miles = kilometers ÷ 1.609344, which is the same as multiplying by 0.621371. For example, 30 km ÷ 1.609344 = 18.64 miles. The other way around: kilometers = miles × 1.609344.
20 km is 12.43 miles, and 30 km is 18.64 miles. Both values are worked out the same way: divide the number of kilometers by 1.609344.
The simplest way is to multiply the number of kilometers by 0.6 — the result is close to the exact figure. You can also use the rule "8 kilometers is 5 miles": 16 km is about 10 miles, and 80 km is about 50 miles. For precise results, use the converter.
200 km is 124.27 miles. Calculation: 200 ÷ 1.609344 = 124.27 miles.
