About Thou (th)

One thousandth of an inch (25.4 micrometers), the thou -- also called a mil in North America -- is used in precision engineering, wire gauge measurement, and plastic film thickness. Circuit board copper foil, paint coatings, and automotive clearances are commonly specified in thou for sub-millimeter precision in imperial contexts.

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.
