About Converting Points to Micrometers
Point and Micrometer both measure length. Specifically: A desktop publishing point is 1/72 inch, and micrometer is 0.000001 meter units.
Formula
micrometers = points × 352.7777778
This factor comes from each unit's defined relationship to the category's base unit: 1 point equals 0.0003527777778 base units, and 1 micrometer equals 0.000001 base units, so dividing one by the other gives the direct point-to-micrometer factor of 352.7777778.
Simple example
1 pt × 352.7777778 = 352.7777778 um
1 point = 352.7777778 micrometers.
Real-world example
10 pt × 352.7777778 = 3,527.777778 um
10 points = 3,527.777778 micrometers.
