400 U.S. mesh = 37 microns
325 mesh is a sieve with o,o44 mm openings.
100 microns = 3.93700787 mils
1 mm = 1000 microns so 0.1 mm = 100 microns.
1 mm = 1000 000 microns 0.1 mm = 100 000 microns
100 microns is 20 times thicker than 5 microns
millionths of what, if inch then 2.54 microns if metre then 100 microns
4 microns is smaller. 600 messh related to openings per square inch. The thickness of screen wire must be reduced from this opening size. For example, 500 mesh screens are rated to have an average 25 microns opening size. For 600 mesh this comes to approximately 21 microns.
