There are 1000 microns in one millimetre. Therefore, 10 millimetres is equal to 1000 x 10 = 10000 microns.
It would be 10 picometres or 0.00001 microns
There are 25400 microns in one inch. Therefore, to convert inches to microns, multiply by 25400. For example, 10 inches is equal to 10 x 25400 = 254000 microns.
