Mile (US Survey)

The US survey mile is a unit of length used in land surveying in the United States. It is defined as exactly 5,280 survey feet, with one survey foot equal to 1200/3937 meters (approximately 0.3048006096 meters). This makes the US survey mile equal to about 1,609.3472 meters, slightly longer than the international (statute) mile, which is exactly 1,609.344 meters.

The US survey mile was established to maintain consistency with older land measurement systems based on the Mendenhall Order of 1893. It was commonly used in mapping, legal land descriptions, and public land surveys.

Although the difference between the survey and statute mile is very small (about 3.2 millimeters), it can be significant over large distances. As of 2023, the U.S. has officially retired the survey foot (and survey mile) for most applications, favoring the international foot and mile to standardize measurements.

Astronomical Unit (a.u.) of Length

The astronomical unit (a.u.) is a unit of length used primarily in astronomy to describe distances within our solar system. It is defined as the average distance between the Earth and the Sun.

Key facts:

1 astronomical unit ≈ 149,597,870.7 kilometers (about 93 million miles)
Used to measure distances between planets and other objects in the solar system
Provides a convenient scale for expressing space distances that are too large for kilometers but too small for light-years

The astronomical unit helps astronomers communicate and calculate orbits, planetary positions, and space missions with clarity and precision.
