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 foot (symbol: ft), plural feet, is a unit of length in the Imperial System and United States customary system. One foot is defined as exactly 12 inches or 0.3048 meters. It is commonly used for measuring height, room dimensions, buildings, land, and construction materials.

The foot remains one of the most widely used non-metric units, especially in the United States and many engineering and construction applications worldwide.

Zettameter (symbol: Zm) is a metric unit of length equal to one sextillion (10²¹) meters. One zettameter is exactly equal to 1 quintillion kilometers, 1 trillion gigameters, or 0.001 yottameter. The zettameter is used to express extraordinarily large distances in cosmology, astrophysics, and theoretical astronomy, where conventional units such as kilometers or astronomical units become impractical. It provides a standardized SI unit for representing distances on an intergalactic or cosmic scale.
