The size of contaminants and particles are usually described in microns, a metric unit of measure where. one micron is one-millionth of a meter. 1 micron = 10-6 m = 1 μm. In imperial units. 1 inch = 25400 microns. 1 micron = 1 / 25400 inch. The eye can in general see particles larger than 40 microns. Typical size of contaminants and particles
