Micron, mil, and millimeter conversions
One micron is one micrometer (0.001 mm). One mil is one-thousandth of an inch and equals 25.4 microns.
1 mil = 25.4 µm | 1 mm = 1000 µm
Packaging use cases
These units are commonly used for films, liners, coatings, foils, tapes, and other thin materials. A thickness conversion does not by itself identify basis weight or density.
