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.

Light Year

A light year is a unit of distance used in astronomy to measure how far light travels in one year. Light moves extremely fast—about 299,792 kilometers per second—so in one year, it travels roughly 9.46 trillion kilometers (or about 5.88 trillion miles). Light years help scientists express the huge distances between stars and galaxies. For example, the nearest star to Earth, Proxima Centauri, is about 4.24 light years away. The term “light year” can be confusing because it sounds like a measure of time, but it actually measures distance.
