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.

Chain

A chain is a unit of length traditionally used in land surveying. The most common version is the Gunter’s chain, which equals 66 feet or 22 yards, approximately 20.1168 meters.

The chain was introduced by English clergyman Edmund Gunter in the 17th century to simplify land measurement. One chain consists of 100 links, each 0.66 feet long. It became a standard unit in British and American land surveying and was instrumental in defining land areas, especially in the U.S. Public Land Survey System.

Key Conversions:

• 
  

  1 chain = 66 feet

  
  
• 
  

  1 chain = 22 yards

  
  
• 
  

  1 chain ≈ 20.1168 meters

  
  
• 
  

  10 chains = 1 furlong

  
  
• 
  

  80 chains = 1 mile

  
  

Though now largely replaced by metric units and modern surveying tools, the chain still appears in older land deeds, maps, and rural property descriptions.
