How to Convert Tyler Screen Size from Microns to Inches

Converting the Tyler mesh screen size from microns to inches is sometimes required when trying to determine whether granular materials like peanuts, fertilizer, grain, and rice contain too many bad pieces. The process is developed by placing a large quantity of a granular material on a Tyler mesh to determine how many pieces fall through the openings. The key to doing this correctly, however, lies in utilizing the correct mesh screen size for the specific granular material.

Instructions

- 1
  Familiarize yourself with the relationship between microns and inches. One micron is equal to one twenty-five thousandth of an inch, and microns are a unit of measurement for granular particle size. Microns are used only when a particle is so small that 325 to 400 holes are needed per linear inch of screen.

  Setup an equation. Because a micron (M) is equal to one twenty-five thousandth of an inch (I), you can construe that every inch is equal to 25,000 microns, or:
  
  I * 25,000 = M
  
  By isolating the inch (I), the equation turns into the following:
  
  I = M / 25,000

  Convert microns to inches. For example, if you need to convert 2000 microns to inches, the equation would be I = 2000 / 25,000, which is equal to 0.08 inches.
