What is KM?

KM stands for kilometres. It is a unit of measurement used to measure distance. Kilometres are commonly used in many countries around the world, especially in Europe and most parts of Asia.

History OF KM

The concept of kilometres can be traced back to ancient Greece, where it was used for measuring distances between different cities and landmarks. The word “kilometre” itself comes from the Greek words “kilo,” which means a thousand, and “metron,” which means measure. This suggests that a kilometre is a measurement of a thousand meters.

What is Miles?

Miles are another unit of distance measurement, commonly used in the United States, the United Kingdom, and a few other countries. It is part of the imperial system of measurement.

History OF Miles

The origin of miles can be traced back to ancient Rome, where they used a unit called “mille passus,” which means a thousand paces. Over time, this evolved into the modern mile we use today.
