About Nautical Miles
A nautical mile (nmi) is equal to 1,852 meters or approximately 1.15078 statute miles, based on one minute of arc along Earth's meridian. This unit is the standard for maritime and aviation navigation worldwide because it directly relates to Earth's geometry, making navigation calculations simpler. Ships and aircraft measure speed in knots (nautical miles per hour). The distance between parallels of latitude is almost exactly 60 nautical miles. International maritime law uses nautical miles to define territorial waters and exclusive economic zones.
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.
