Distance measurement refers to the process of determining the space between two points. This can be done using various methods, including physical tools like rulers and tape measures, or more advanced technologies such as laser rangefinders and GPS systems. Accurate distance measurement is essential in fields like construction, surveying, and navigation. Different units are used to express distance, such as meters, kilometers, miles, and feet. The choice of unit often depends on the context and the region. For example, in many countries, the metric system is standard, while others, like the United States, commonly use the imperial system.
