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 themeter (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 kilometer (1 km = 1,000 m) for distances and the centimeter (cm) and millimeter (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 light-year (symbol: ly) is a unit of distance, not time. It's one of the most common units astronomers use to measure the truly vast distanc......(Read more on Light Year).

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.
