Ångström

An ångström (symbol: Å) is a unit of length commonly used in physics, chemistry, and biology to measure very small distances, such as atomic and molecular scales. It is equal to 10⁻¹⁰ meters, or 0.1 nanometers (nm).

The unit is named after the Swedish physicist Anders Jonas Ångström, who made significant contributions to spectroscopy.

Key facts:

• 
  

  1 ångström = 10⁻¹⁰ meters = 0.1 nanometers

  
  
• 
  

  Used to measure atomic and molecular sizes, wavelengths of light, and crystal lattice constants

  
  
• 
  

  Common in fields like crystallography, chemistry, and materials science

  
  

Though largely replaced by the nanometer in the SI system, the ångström remains widely used in scientific literature to describe very small lengths.

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

  
  
• 
  

  1 fathom = 2 yards

  
  

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.
