Definition
丝米 is a measure word (classifier) for the unit of length equal to 0.0001 meters, called a decimillimeter. It's a very precise unit used mainly in science, engineering, and manufacturing contexts where millimeter-level precision is insufficient. When you use 丝米, you combine it directly with a number: 一丝米 (one decimillimeter), 两丝米 (two decimillimeters), and so on.
