About these units
km (kilometres): Long distances and pipelines.
µm (micrometres (microns)): Surface finish and fine tolerances.
The international inch is exactly 25.4 mm. A mil (or thou) is a thousandth of an inch, used for coating, film and tolerance values; do not confuse it with the millimetre.
