About Micrometer (µm)

One millionth of a meter, the micrometer (or micron) is essential in semiconductor manufacturing, biology, and materials science. Human red blood cells measure about 7 micrometers across, and chip fabrication processes are named by their transistor gate length in micrometers or nanometers.

About Astronomical Unit (au)

Originally based on Earth's mean distance from the Sun, the astronomical unit (AU) was fixed in 2012 at exactly 149,597,870,700 meters. Planetary scientists use AUs to express distances within the solar system: Mars orbits at about 1.52 AU, Jupiter at 5.2 AU, and the outer edge of the Kuiper Belt at roughly 50 AU.
