Here is the plastic gauge thickness conversion chart, you can check some data directly. Plastic gauge is different from wire gauge for plastic gauge measurement, the larger the gauge, the thicker the film.
Note:
1. Gauge is usually reserved for thicknesses below 1 mil.
2. Mil is a US unit of measurement and Micron (um or Micrometer) is a metric system measurement of thickness.
3. Microns measurements are usually rounded to the nearest whole integer. For example, 7.62 microns is usually expressed in 7.6.
4. Mil to Micron conversion is usually the most important conversion to make when working with flexible barrier plastics.
