Hand

A hand is a traditional unit of length primarily used to measure the height of horses. It is equal to 4 inches or 10.16 centimeters.

The origin of the hand as a measurement comes from using the width of a human hand, and it has been standardized at 4 inches for consistency in horse measurement. Horse height is expressed in "hands," measured from the ground to the highest point of the withers (the ridge between the shoulder blades).

Key points:

• 
  

  1 hand = 4 inches

  
  
• 
  

  1 hand = 10.16 centimeters

  
  
• 
  

  Used mainly for measuring horse height

  
  
• 
  

  Horse height is often given in hands and inches, e.g., 15.2 hands means 15 hands plus 2 inches

  
  

The hand remains the standard unit for horse height in many English-speaking countries.

Micrometer

A micrometer (µm), also called a micron, is an extremely small unit of length in the metric system. It is equal to one-millionth of a meter (0.000001 meters). Micrometers are used to measure tiny objects that are invisible to the naked eye, such as bacteria, cells, or the thickness of a human hair (which is about 50 to 70 micrometers thick). The symbol for micrometer is "µm". This unit is very important in science, engineering, and manufacturing where precise measurements are needed at microscopic scales. Because it is so small, the micrometer helps scientists study the details of very small structures.
