How can kilometers be converted into miles according to the training material?

To convert kilometers into miles accurately, using the provided method of multiplying kilometers by 6 and dropping the last digit is a quick approximation often used. When you multiply kilometers by 6, the result is close to the equivalent distance in miles, especially for common distances. Dropping the last digit simplifies the conversion and provides a rough estimate that is easy to calculate in your head.

In detail, the precise conversion factor between kilometers and miles is approximately 0.621371. However, since 6 divided by 10 is 0.6, this approximation remains useful for easy calculations without access to a calculator. While this method is practical for quick estimations, more accurate methods involve using the precise factor of 0.621371 for conversions when exact distances are needed.
