How to convert micrometer to millimeter
One micrometer equals 0.001 mm, so multiply the number of micrometers by 0.001:
mm = µm × 0.001
Going the other way
One millimeter equals 1000 µm, so to convert back:
µm = mm × 1000
Both directions are shown in the results above, and the drop-downs let you convert between any pair of length units — not just these two.
