Millimeter

A millimeter (mm) is a very small unit of length in the metric system. It is commonly used to measure tiny objects or precise dimensions. One millimeter is equal to one-thousandth of a meter (1 mm = 0.001 m), and 10 millimeters make 1 centimeter. Millimeters are often used in fields like engineering, machining, and science where exact measurements are important. For example, the thickness of a credit card is about 1 mm. The symbol for millimeter is "mm", and you can find it on most rulers or measuring tools. Since it allows for high accuracy, the millimeter is ideal for measuring small parts, gaps, or details.

Fermi

A fermi is a unit of length used in nuclear physics to measure extremely small distances, such as the size of atomic nuclei. It is equal to 1 femtometer (fm), which is 10⁻¹⁵ meters.

The unit is named after the Italian physicist Enrico Fermi, known for his work in nuclear physics.

Key facts:

• 
  

  1 fermi = 1 femtometer = 10⁻¹⁵ meters

  
  
• 
  

  Used to measure nuclear dimensions and particle sizes

  
  
• 
  

  Essential in the study of nuclear and particle physics

  
  

The fermi is vital for describing distances at the subatomic scale, much smaller than atoms and molecules.
