Fathom (US Survey)

The fathom (US survey) is a unit of length used in U.S. surveying and nautical contexts, defined as exactly 6 US survey feet. Since one US survey foot is approximately 0.3048006096 meters, the US survey fathom measures about 1.828804 meters.

Like the international fathom, it is primarily used to measure water depths and underwater distances in marine navigation and surveying.

Key details:

• 
  

  1 US survey fathom = 6 US survey feet

  
  
• 
  

  1 US survey fathom ≈ 1.828804 meters

Though the difference between the US survey fathom and the international fathom is very small, the US survey units are being phased out in favor of international standards, but they still appear in some legal and historical surveying documents.

Cubit (Greek)

The Greek cubit is an ancient unit of length based on the forearm’s length—from the elbow to the tip of the middle finger. In ancient Greece, it typically measured about 18 to 20 inches (approximately 45 to 50 centimeters), though the exact length could vary by region and period.

The Greek cubit was widely used in architecture, construction, and land measurement. It played a crucial role in building temples, monuments, and other structures in classical Greece.
