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.

Ell

An ell is a historical unit of length that was commonly used in medieval Europe, especially for measuring textiles and cloth. Its length varied by region but was typically about 45 inches (approximately 1.143 meters).

The ell originated from the length of the arm or forearm and was often used by tailors and merchants to measure fabric. Different countries had their own versions—for example, the English ell was about 45 inches, while the Scottish ell was longer, around 37 inches.

Although obsolete today, the ell played an important role in trade and clothing production before standardized measurements became widespread.

Summary:

• 
  

  1 ell ≈ 45 inches (1.143 meters)

  
  
• 
  

  Used mainly for measuring cloth and textiles

  
  
• 
  

  Length varied by region and country

  
  

The ell is now largely of historical interest but reflects the origins of many modern measurement systems.
