## Master to Convert Km To Miles Through This Method

In this article, we'll show you a quick tip to convert km to miles so that you can avoid making calculation errors that could cost you points. Before learning the trick, it's important to comprehend what a mile and a kilometer are and why converting these units is important. Both mile and kilometer are units of distance.

History of miles: Miles have their origins in Roman culture when 5000 Roman feet was considered one mile. The English Parliament established the Mile as eight furlongs (one furlong is 660 feet) in 1592. On July 1, 1959, an international agreement standardized the mile's precise measurement as 1609.344 meters. This unit is called the Imperial or USA customary unit and is primarily used in the United States and the United Kingdom.

History of km: Kilometres are the unit of measurement in the metric system. While many different systems have been referred to as metrics over the years, the metric system was not standardized into what we know it as today until the 1960s. In France, this system is referred to as the "Système International d'Unités," which is abbreviated to the "SI" unit. Thus, a kilometer is the SI unit of length and is used by most nations of the world to calculate distance. One kilometer equals to 1000 meters.

## Converting miles to km:

Do you know what 50 miles in km is? While the answer is 80.467 km, the calculation is a complex affair. Always keep in mind that 1 mile is equal to 1.6 kilometers. Now all you need to do is to multiply 50 by 1.6, and you will get 80. 467 km. Remember to not forget the "kilometers" label or "km" for short after the numerical, else you will lose points.

However, according to the official U.S. Survey definition, one mile equals 1.609347218694 km. Thus, for precise conversion of miles to km, one needs to multiply 50 by 1.609347218694, and the exact answer will be 80.4673609347 km.

## How to convert km to miles:

The oldest trick to convert km to miles is multiplying the number by 0.62137119. It is very difficult to do this calculation, and there is a high probability that you will make some mistakes while doing the calculation.

We can break down this calculation in the following steps:

1. Let’s consider the number of kilometers to be 100. Now halve it and you will get 50. Now take a quarter of half, i.e, 12.5.
2. Now, all you need is to add the half and the quarter together, i.e, 50 plus 12.5. You will get 62.5, which is the answer.

Isn’t this step quite tricky to remember? There is a high probability you might skip a step and thus get a wrong result. So, here we provide you with an easy way to convert km to mile or miles to km. Use our A2Z calculator to convert km to the mile or vice versa.
