Micron
A micron (µ) is another name for the micrometer and equals one-millionth of a meter. Although the term “micrometer” is the official scientific unit, “micron” is still widely used in fields like biology, manufacturing, and material science. This tiny unit helps measure fibers, particles, and microscopic structures.
Because microns are so small, they are essential in technologies such as air filtration, semiconductor production, and optical equipment. Converting microns to millimeters or nanometers is easy with a converter, making high-precision work more manageable.
Astronomical Unit
An astronomical unit (AU) is a standard space measurement based on the distance from the Earth to the Sun—about 149.6 million kilometers or 93 million miles. It helps describe solar system distances in practical numbers rather than extremely large values.
Astronomers use AU values to measure orbits of planets, asteroids, and comets relative to Earth.
