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.
Earth’s Distance from the Sun
The average distance between the Earth and the Sun is known as an Astronomical Unit (AU).
It is approximately 149.6 million kilometers (about 93 million miles).
This distance varies slightly throughout the year because Earth’s orbit is elliptical—closest at perihelion (~147.1 million km) and farthest at aphelion (~152.1 million km).
The astronomical unit is a fundamental standard for measuring distances within our solar system.
Key facts:
Average distance ≈ 149.6 million km (1 AU)
Varies due to elliptical orbit
Basis for measuring planetary distances
Understanding Earth’s distance from the Sun is essential for studying seasons, climate, and orbital mechanics.
