Convert Thou (mil) to Micrometers

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

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

Going the other way? Convert µm to thou.
