Fathom

A fathom is a unit of length traditionally used to measure the depth of water. It equals 6 feet or approximately 1.8288 meters.

Originating from the Old English word fæðm, meaning "to embrace" or "outstretched arms," the fathom was based on the average distance between a person's outstretched arms. It has been widely used by sailors and navigators to estimate sea depths and underwater distances.

Key facts:

1 fathom = 6 feet
1 fathom ≈ 1.8288 meters
1 fathom = 2 yards

Though modern sonar and electronic instruments now measure depth more precisely, the fathom remains a traditional unit in nautical contexts, especially in maritime charts and historical references.

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.
