100 microns is 20 times thicker than 5 microns
100 microns is 3937 millionths of an inch
To convert microns to grams per square meter (gsm), you need to know the basis weight of the material in question. The basis weight is the weight in grams of one square meter of the material. Once you have the basis weight, you can use the formula: gsm = (basis weight in g/m²) / (thickness in microns). So, without the basis weight, it is not possible to accurately convert 100 microns to gsm.
It is 7*100 microns.
1 mm = 1000 000 microns 0.1 mm = 100 000 microns
