Convert Micrometers to Thou (mil)

Micrometers → Thou (mil)
µm × 0.03937008 = thou thou × 25.4 = µm

To convert micrometers (µm) to thou (mil) (thou), multiply the micrometers value by 0.03937008. 1 µm = 0.03937008 thou, and 1 thou = 25.4 µm. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert thou to µm.
