Length is the measure of distance in one dimension—the extent of an object from one end to the other, or the distance between two points. The SI base unit is the metre (m), defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second. Common derived units include the kilometre (km = 1,000 m) for distances and the centimetre (cm) and millimetre (mm) for everyday measurements. US customary length units include the inch (in), foot (ft), yard (yd), and mile (mi). The nautical mile (1,852 m) is used in aviation and maritime navigation.

A kilometer (km) is a metric unit of length equal to 1,000 meters. The kilometer is the standard unit for measuring distances between cities, geographic features, and large-scale terrestrial measurements in countries using the metric system. Road signs, maps, and navigation systems worldwide display distances in kilometers. Scientific research, engineering projects, and everyday travel calculations rely on kilometers as the practical unit for distances larger than a few hundred meters. The kilometer integrates seamlessly with the broader metric system, making conversions to meters, centimeters, and other units straightforward. Learn more about kilometer.

A thousandth of an inch (0.001 in or 1 mil) is a precision measurement unit standard in American manufacturing, machining, and engineering. The unit represents one thousandth of an inch, providing practical precision for mechanical tolerances and component specifications without requiring small decimal notation. American machine shops, precision instrument manufacturers, and aerospace suppliers specify component tolerances using thousandths of inches. Micrometers and precision measuring instruments in American facilities calibrate and display measurements in thousandths of inches. Despite metric conversion efforts, the unit remains embedded in American industrial standards, legacy equipment, and technical documentation. Engineers and machinists trained in the American system continue using thousandths of inches in routine work.
