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.

Roman Actus

The actus was an ancient Roman unit of length used primarily in land measurement. It is approximately 120 Roman feet, which equals about 35.5 meters (around 116.5 feet).

The actus was often used to define dimensions of fields and plots of land. It was also part of Roman surveying practices, helping organize land division and property boundaries.

Key facts:

• 
  

  1 actus = 120 Roman feet ≈ 35.5 meters

  
  
• 
  

  Used in Roman land surveying and agriculture

  
  
• 
  

  Essential for measuring fields and agricultural plots

  
  
• 
  

  Reflects the Roman emphasis on precise land division

  
  

The actus highlights the sophistication of Roman engineering and property management in their time.
