Gigameter

A gigameter (Gm) is a unit of length in the metric system, equal to 1 billion meters (1 Gm = 10⁹ meters). Gigameters are used to measure very large distances, often within the solar system. For example, the average distance from Earth to the Sun is about 150 gigameters, or 1 astronomical unit (AU). While not commonly used in everyday life, gigameters are helpful in astronomy and space science to describe distances between planets or other celestial bodies.

Mil

A mil is a unit of length commonly used in engineering and manufacturing to measure very small distances, especially thicknesses. It is equal to one-thousandth of an inch (0.001 inch), which is approximately 0.0254 millimeters.

The mil is widely used in industries like plastic film, coatings, wire diameter, and mechanical parts, where precise measurements of thin materials are necessary. It should not be confused with the millimeter, which is 0.001 meters or 1,000 microns — much larger than a mil.

Key points:

• 
  

  1 mil = 0.001 inch = 0.0254 mm

  
  
• 
  

  Used mainly for small thicknesses or diameters

  
  
• 
  

  Common in engineering, manufacturing, and material sciences

  
  
• 
  

  Not to be confused with millimeter (mm)

  
  

The mil remains an important unit in technical fields where fine measurement is critical.
