Km To Miles | Kilometers To Miles (km to mi) Conversion

Jan 15, 2023 9:27 PM

Km to miles converter is a conversion tool that helps you to convert kilometers to miles.  Both the kilometers and the miles are the units to measure length but in different measurement systems used in various countries, so this converter is especially helpful to those who aren't familiar with the kilometer, a metric unit of length. 

Kilometer (Kilometre) - Unit of distance measurement in many countries

The kilometer is a unit of length in the International System of Units (SI), commonly known as the metric system. As its prefix “kilo” indicates, one kilometer equals 1000 meters. The unit is abbreviated as km and with different accents of English, it can be spelled as “kilometer” (American English) or kilometre (British English). This unit of length is often used to show the distance between two places in many countries where the metric system is adopted. 

At the present, the unit is defined as the length of the path traveled by light in a vacuum during a time interval of 1/299792458 of a second.

Mile, is it used more widely than the kilometer?

The mile is a unit of distance in the US customary system or the Imperial system, equal to 1,760 yards or 1.6 kilometers. The mile can be abbreviated as "mi", "M", "ml", and "m". To avoid confusion with metric units of the meter (m) and millimeter (ml), “mi” is recommended. Together with kilometers, the mile is a common unit used to show the distances between places and it is widely used in English-speaking countries such as the USA

Originally, the term “mile” comes from a Roman word “mille passuum”, which means a thousand paces. However, with the development of length measurement, the mile we often mention today is the international mile or statute mile, which has been standardized to reach an agreement worldwide. 

How many kilometers in a mile?

One mile equals 1.609344 km. Hence, 1 km is equal to 0.621371 mi.

Relationship between kilometers to miles

In the metric system, a kilometer is a unit of distance, whereas a mile is a corresponding unit in the British imperial or US customary systems. These are the two most commonly used units of distance with international recognition, but the kilometer is used by more countries. Some countries that previously used the imperial system have now switched to the metric system but continue to use miles as a unit of distance. The United Kingdom is a good example. Because kilometers and miles are widely used units of distance, we must convert km to miles and vice versa on a regular basis. The relationship between km and miles can be simplified as follows:

1 kilometer equals 0.621371 mile 

1 mile equals 1.609344 km 

To reduce your memory load, you can remember that 1 km = 0.6 mi, and 1 mi = 1.6 km.

Differences between kilometers and miles

The similarities and differences between kilometers and miles can be summarized in the following table.





A kilometer is a unit of length in the metric system defined as the length of the path traveled by light in a vacuum during a time interval of 1/299792458 of a second.

A mile is a unit of distance in the US customary system or the Imperial system, equal to 1,760 yards or 1.6 kilometers.



mi, "M", "ml", and "m". Among them, mi is the most common. 


The kilometer is widely used in all countries adopting the metric system to describe distances except the UK.

The mile is mainly used in the USA, Liberia, Myanmar, and such countries like the UK which have switched to the metric but still keep miles to measure distances.


1 km = 1.609344 mi

1 mi = 0.621371

How to convert kilometers to miles (km to miles)

Since kilometers are used in many countries, Americans may need to convert them into miles, a more common unit of distance in the USA. 

To convert kilometers into miles, you multiply the distance value by 0.621371 because 1 km equals 0.621371 mi. The following is the formula:

miles = kilometers × 0.621371

However, the fastest way is to use a converter like this Calculatorful's kilometer to mile converter. The only step you need to do is to key the value in kilometers in the kilometer field and see the answer.

Example 1: Convert 50 km to miles

Applying the previously mentioned formula, miles = kilometers x 0.621371, we have:

Miles = 50 x 0.621371

= 31.06855 mi

Example 2: Convert 30 km to miles

Since miles = kilometers x 0.621371, we have:

Miles = 30 x 0.621371

= 18.64113 mi

So, 30 km is equal to 18.64113 mi

Example 3: Convert 70 km to miles

Applying the previously mentioned formula, miles = kilometers x 0.621371, we have:

Miles = 70 x 0.621371

= 43.49597 mi

Thus, 70 km is equivalent to 43.49597 mi
