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.

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.
