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.

The barleycorn is a traditional unit of length equal to one-third of an inch (0.3333 in or 8.4667 mm). Historically based on the average length of a grain of barley, it has been used in the British Imperial and U.S. customary systems, particularly for measuring shoe sizes. Learn more about length.

One barleycorn is equal to 0.333333 inch, 8.46667 millimeters, 0.846667 centimeter, and 0.00846667 meter. Although rarely used as a general unit today, the barleycorn remains important in traditional shoe sizing systems and historical measurement references.

Zeptometer (symbol: zm) is a metric unit of length equal to one sextillionth (10^-21) of a meter. One zeptometer is exactly equal to 0.001 attometer, 1,000 yoctometers, or 1 × 10^-9 picometer. The zeptometer is used in theoretical physics, particle physics, and quantum mechanics to describe extremely small distances far below the scale of atoms. It provides a standardized SI unit for expressing subatomic dimensions and scientific calculations involving elementary particles.
