Planck Length

The Planck length is the smallest meaningful unit of length in physics, representing a fundamental scale at which classical ideas about gravity and space-time break down and quantum effects dominate.

• 
  

  It is defined as approximately 1.616 × 10⁻³⁵ meters.

  
  
• 
  

  The Planck length is derived from fundamental constants: the speed of light, Planck’s constant, and the gravitational constant.

  
  
• 
  

  It sets a theoretical limit below which the very concepts of space and distance may lose conventional meaning.

  
  
• 
  

  Used mainly in theories of quantum gravity and string theory.

  
  

Key facts:

• 
  

  1 Planck length ≈ 1.616 × 10⁻³⁵ m

  
  
• 
  

  Smallest scale in quantum physics and cosmology

  
  
• 
  

  Represents a scale where quantum effects of gravity become significant

  
  

The Planck length is crucial for understanding the fabric of the universe at its most fundamental level.

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.
