About micrometers and millimeters
A micrometer (micron, µm) is one millionth of a meter or one thousandth of a millimeter. Filters, fibers, bacteria and coating thicknesses are measured in microns.
A millimeter is one thousandth of a meter (0.1 cm). It is used for small, precise measurements like rainfall, screws and paper thickness.
