About Mil/Thou
A mil (or thou) is one thousandth of an inch, 25.4 micrometres. US manufacturing uses it for sheet, film and coating thickness.
Common uses: plastic film, PCB traces, coating thickness.
About Picometer
The picometer (pm) is a unit of distance and length. One picometer equals 1.000000 × 10^-12 metres. UnitConvertLab converts it against every other length unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: length calculations, engineering and science, education.
