Nautical Mile (International)

A nautical mile (international) is a unit of measurement used primarily in maritime and aviation contexts. It is defined as 1,852 meters or 1.852 kilometers, which is approximately 1.1508 statute miles. The nautical mile is based on the Earth's geometry, representing one minute of latitude along any meridian. This makes it particularly useful for navigation, as distances on charts and GPS systems often relate directly to degrees of latitude and longitude. The international nautical mile was officially adopted by the United States in 1954 and is now used worldwide for consistency in global navigation. It is closely linked with the knot, a unit of speed equal to one nautical mile per hour. The standardization of the nautical mile has greatly simplified communication and coordination in international travel, trade, and defense across oceans and airspace. Its use continues to be essential in global navigation systems today.

Astronomical Unit

An astronomical unit (AU) is a unit of distance used in astronomy to describe the average distance between the Earth and the Sun. It equals about 149.6 million kilometers (or about 93 million miles). The AU is useful for measuring distances within our solar system, such as the distance from Earth to other planets. For example, Mars is about 1.5 AU from the Sun. Using the AU makes it easier to understand and compare distances between planets without dealing with very large numbers. The symbol for astronomical unit is "AU".
