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.
About Fathoms
A fathom (ftm) is equal to 6 feet or 1.8288 meters, traditionally based on the span of a man's outstretched arms. This unit has been used for centuries in maritime navigation to measure water depth and rope or cable lengths. While largely replaced by meters in modern nautical charts, fathoms remain in use by sailors and in naval traditions. The Mariana Trench, Earth's deepest point, reaches about 6,000 fathoms. The term 'to fathom' meaning 'to understand' derives from this nautical unit.
