Furlong (US Survey)

The furlong (US survey) is a traditional unit of distance used in U.S. land surveying, defined as 1/8 of a U.S. survey mile, or exactly 660 U.S. survey feet. Since one U.S. survey foot equals approximately 0.3048006096 meters, the US survey furlong is about 201.1684 meters long.

While the difference between the US survey furlong and the international (standard) furlong is extremely small (just a few micrometers), it was significant in precise land measurements, particularly in legal and cadastral surveying contexts.

Key Conversions:

1 US survey furlong = 660 US survey feet
1 US survey furlong ≈ 220 yards
1 US survey furlong ≈ 201.1684 meters
8 US survey furlongs = 1 US survey mile

As of 2023, the U.S. has officially deprecated the use of the survey foot (and by extension the survey furlong) in favor of the international foot, but it may still appear in historical and legal documents.

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.
