20 microns is 0.002cm
100 microns is 20 times thicker than 5 microns
1 mm = 1000 microns. 20/1000=.02mm
1 mm = 1000 microns so 0.02 mm = 0.02*1000 = 20 microns. Simple!

20 microns is 0.002cm
The size of a virus typically ranges from about 20 to 400 nanometers (0.02 to 0.4 microns), making them significantly smaller than most bacteria.
I found a Water Quality Standards chart for a geothermal heat pump and one part of it says "Filtered fo maximum 800 microns [800mm, 20 mesh] size." So I would guess its 20.
100 microns is 20 times thicker than 5 microns
500 to 0 microns
They vary from 0.05 microns to 100 microns.
"20 microns" is a size measurement that has very little indeed to do with evaluating a piece of jewelry. More applicable would be someting like karat markings or carat weight.
1 mm = 1000 microns. 20/1000=.02mm
A rhinovirus is approximately 30 nanometers (nm) in size, which is equivalent to 0.03 microns.
HIV is about 0.1 microns in size. Hope this helps! Dr. B.
10cm is 100,000um. 100,000/20 is 5000 magnification
To convert 20 microns to millimeters, divide by 1000: 20 microns = 20/1000 = 0.02 mm Then, divide 0.02 mm by 20 mm: 0.02 mm / 20 mm = 0.001
