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 astronomical unit (symbol: AU, au, or ua) is a unit of length defined as exactly 149,597,870,700 meters. It is based on the average distance between the Earth and the Sun and is widely used to express distances within the Solar System. Learn more about the meter and length.

One astronomical unit is equal to 149,597,870,700 meters, 149,597,870.7 kilometers, 92,955,807.27 miles, and 0.0000158125 light-years. It is commonly used in astronomy, astrophysics, planetary science, and space exploration to describe distances between planets, asteroids, and the Sun.

Yoctometer (symbol: ym) is a metric unit of length equal to one septillionth (10^-24) of a meter. One yoctometer is exactly equal to 0.001 zeptometer, 1,000 quectometers, or 1 × 10^-6 attometer. The yoctometer is one of the smallest SI units of length and is used in theoretical physics, quantum mechanics, and particle physics to describe distances at the subatomic scale. It provides a standardized metric unit for representing extremely small dimensions in advanced scientific research.
