About Thou
A thou (also called mil) is one thousandth of an inch, equal to 0.0254 millimeters or 25.4 micrometers. This unit is commonly used in engineering and manufacturing in countries that use imperial measurements, particularly for specifying tolerances, wire gauges, and thin material thicknesses. For example, a standard plastic bag might be 1-2 thou thick, a sheet of paper is about 4 thou, and precision machined parts often have tolerances measured in thou. Electronic circuit board copper traces are typically 1.4 thou thick.
About Megaparsecs
A megaparsec (Mpc) is one million parsecs or 3.26 million light years, the standard unit for measuring intergalactic distances. The Andromeda Galaxy is about 0.77 megaparsecs away, while most galaxies in the observable universe are measured in megaparsecs. The Local Group of galaxies spans about 3 megaparsecs. Astronomers use megaparsecs in combination with redshift measurements to calculate distances to distant galaxies and study the expansion of the universe. The Hubble constant, describing cosmic expansion, is expressed in kilometers per second per megaparsec.
