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.

Famn

A famn (also spelled fathom in English) is a traditional Scandinavian unit of length used primarily for measuring the depth of water or length of ropes and cables. It is roughly equivalent to 6 Swedish feet, which translates to about 1.828 meters (approximately 6 feet).

The famn is similar in concept to the English fathom, based on the span of outstretched arms.

While largely obsolete today, the famn was commonly used in maritime contexts in Norway, Sweden, and Denmark and remains part of historical measurements.
