1 mile = 1.6444 km.

Mile is an English unit of measurement, which is often used by many countries in the world to indicate the distance between two places. Kilometers are also units of measurement, but they are metric units of length. The conversion between kilometers and miles only needs a simple mathematical formula.

Extended data:

There are three ways to convert kilometers into miles:

1. Convert kilometers to miles.

1 km is equal to 0.62 137 1 mile, usually rounded to the nearest 0.62 mile. And 1 mile equals 1.6044 km. Therefore, to convert kilometers into miles, just multiply the number of kilometers by 0.62 137.

Suppose you run 5 kilometers, people usually want to know how many miles 5 kilometers equals, and then you have to convert it. The formula is 5X0.62 137=3. 1 mile.

You can also divide the number of kilometers by the number of kilometers per mile, which is 1.609 kilometers mentioned above. For simplicity, it can be rounded. For example, 5 km1.609 km/mile =3. 1 mile.

Second, use a conversion table or an online calculator.

The conversion table lists the kilometers and their corresponding miles. And enter the kilometers in the calculator, and you can get the corresponding miles. For example, the conversion table will show that 1 1 km is equal to 6.84 miles, while 1 1 mile is equal to 17.7 km.

If you can use MicrosoftExcel, you can also use Excel formula for conversion. The formula for converting kilometers into miles in Excel is CONVERT(x, "y", "z"). In the formula, "Y" represents the original unit of measurement, "X" represents the value before the unit, and "Z" represents the unit of measurement to be converted.

Third, use Fibonacci number conversion.

This method is very special and useful. Fibonacci number is a series of numbers, the last of which is the sum of the first two numbers.

Start with two consecutive Fibonacci sequences. For example, the numbers 5 and 8. This means that five miles is equivalent to eight kilometers. You can also look at it the other way around, that is, 8 kilometers is equivalent to 5 miles. This is only the approximate result of estimation. Taking two consecutive Fibonacci numbers 2 1 and 34 as examples, we can know that 2 1 mile is equivalent to 34 kilometers, and vice versa. But the more accurate answer is 33.79 kilometers.

If the number to be converted is not in Fibonacci series, you can imagine the original number as the sum of two Fibonacci numbers, and then convert each Fibonacci number separately. Suppose you want to convert 100 miles into kilometers.

100 can be regarded as the sum of Fibonacci numbers 89+8+3. Fibonacci numbers after 89, 8 and 3 are 144, 13 and 5 respectively. Therefore, 100 mile is equivalent to144+13+5 =162 km.
