Rod

A rod is a traditional unit of length used in land measurement and surveying. It is equal to 16.5 feet, 5.5 yards, or exactly 5.0292 meters.

Also known as a pole or perch, the rod dates back to medieval England and was commonly used for measuring land and agricultural plots. It is closely related to other units such as the chain (which is 4 rods) and the furlong (which is 40 rods).

Key conversions:

• 
  

  1 rod = 16.5 feet

  
  
• 
  

  1 rod = 5.5 yards

  
  
• 
  

  1 rod = 5.0292 meters

  
  
• 
  

  4 rods = 1 chain

  
  
• 
  

  40 rods = 1 furlong

  
  

Though largely replaced by metric units today, the rod is still occasionally used in surveying and legal descriptions of land, especially in the United States and the UK.

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.
