About Converting Points to Nanometers
Point and Nanometer both measure length. Specifically: A desktop publishing point is 1/72 inch, and nanometer is 1e-9 meter units.
Formula
nanometers = points × 352777.7778
This factor comes from each unit's defined relationship to the category's base unit: 1 point equals 0.0003527777778 base units, and 1 nanometer equals 1e-9 base units, so dividing one by the other gives the direct point-to-nanometer factor of 352777.7778.
Simple example
1 pt × 352777.7778 = 352,777.7778 nm
1 point = 352,777.7778 nanometers.
Real-world example
10 pt × 352777.7778 = 3,527,777.778 nm
10 points = 3,527,777.778 nanometers.
