Femtometer

A femtometer (fm) is a unit of length in the metric system, equal to one-quadrillionth of a meter (1 fm = 10⁻¹⁵ meters). It is also known as a fermi, named after the physicist Enrico Fermi. Femtometers are used to measure extremely small distances at the subatomic level, such as the size of protons, neutrons, and atomic nuclei. For example, the radius of a proton is about 0.84 femtometers. This unit is commonly used in nuclear physics and particle physics, but it's far too small for everyday measurements.

Centiinch

A centiinch is a very small unit of length equal to one-hundredth of an inch (0.01 inch). It is not commonly used in everyday measurement but may appear in fields requiring precise fractional measurements based on the inch.

Key details:

• 
  

  1 centiinch = 0.01 inch

  
  
• 
  

  Equivalent to 0.254 millimeters

  
  
• 
  

  Used for fine measurements where inch subdivisions are preferred

  
  
• 
  

  Rare and mostly of specialized or historical interest

  
  

The centiinch allows for more detailed measurements within the inch system, similar to how centimeters subdivide a meter.
