Length conversion Length conversion is the process of converting a distance or length measurement from one unit to another. This is a common task in various fields such as science, engineering, and construction. The most commonly used units of length in the metric system are meters, centimeters, and millimeters. The basic unit of length in the imperial system is the yard, but inches, feet, and miles are also frequently used. To convert between different units of length, a conversion factor is needed. This factor is a ratio that relates the value of one unit to the value of another unit. For example, there are 100 centimeters in one meter, so to convert 5 meters to centimeters, you would multiply 5 by 100 to get 500 centimeters. In addition to converting between different units within a single system of measurement (such as metric or imperial), it is also possible to convert between different systems of measurement. This can be more complex, as the conversion factors between different systems are not always straightforward. For example, to convert from meters to feet (metric to imperial), you would need to use a conversion factor of 3.2808 feet per meter. Here are some units of length: meter (m), centimeter (cm), millimeter (mm), kilometer (km), micrometer (µm), nanometer (nm), inch (in), foot (ft), yard (yd), mile (mi), nautical mile (nmi) and light-year (ly).
