Russian Archin

The archin (also spelled arshin) is a traditional Russian unit of length that was widely used before the adoption of the metric system. It is approximately equal to 28 inches or 0.7112 meters.

The archin was commonly used in measuring cloth, land, and building dimensions in Russia and neighboring regions. It roughly corresponds to the length of a forearm from the elbow to the tip of the middle finger, similar to the cubit.

Though obsolete today, the archin remains an important part of Russian historical measurements and appears in older legal and trade documents.

Summary:

• 
  

  1 archin ≈ 28 inches (0.7112 meters)

  
  
• 
  

  Used historically in Russia for textiles and land measurement

  
  
• 
  

  Based on the length of the forearm

  Mostly of historical and cultural interest today

  
  

Caliber

Caliber is a term used to describe the internal diameter of a cylindrical object, most commonly the inside diameter of a gun barrel or firearm bore. It is typically measured in inches or millimeters.

• 
  

  In firearms, caliber indicates the diameter of the bullet or projectile that can be fired from the barrel (e.g., a .45 caliber means the barrel’s internal diameter is 0.45 inches).

  
  
• 
  

  In other contexts, such as engineering or piping, caliber can refer more generally to the diameter or thickness of tubes or cylindrical objects.

  
  

Key points:

• 
  

  Caliber = internal diameter of a barrel or tube

  
  
• 
  

  Measured in inches or millimeters

  
  
• 
  

  Important for firearm specifications and ammunition compatibility

  
  
• 
  

  Also used in engineering and manufacturing

  
  

Caliber is crucial for matching ammunition to firearms and for defining performance characteristics like velocity and accuracy.
