Distance conversion is the process of changing a measurement of distance from one unit to another. Common units of distance include meters, kilometers, miles, and feet. For example, converting miles to kilometers involves multiplying the number of miles by 1.60934, since one mile is approximately equal to 1.60934 kilometers. This conversion is useful in various fields, such as travel, engineering, and science, where different units may be used. Understanding how to convert distances helps ensure accurate communication and calculations, making it easier to compare measurements across different systems.
