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.

Nanometer (symbol: nm) is a metric unit of length equal to one-billionth of a meter (10^-9 m). One nanometer is exactly equal to 0.000000001 meter, 0.001 micrometer, or 10 angstroms. The nanometer is one of the most widely used units for measuring structures and distances at the nanoscale, where dimensions are too small to be expressed conveniently in larger metric units.

Nanometers are commonly used in nanotechnology, semiconductor manufacturing, optics, molecular biology, chemistry, and materials science. The sizes of nanoparticles, DNA molecules, viruses, semiconductor transistors, and the wavelengths of visible light are often measured in nanometers. Modern computer processors and electronic components are also described using nanometer-scale manufacturing technologies.

As an SI-derived unit, the nanometer is widely used in scientific research, engineering, international standards, and technical documentation. It is closely related to the angstrom, picometer, micrometer, and meter, making it an essential unit for describing dimensions at the atomic, molecular, and nanoscale levels.
