About Converting Points to Gigameters
Point and Gigameter both measure length. Specifically: A desktop publishing point is 1/72 inch, and gigameter is 1000000000 meter units.
Formula
gigameters = points × 3.527778e-13
This factor comes from each unit's defined relationship to the category's base unit: 1 point equals 0.0003527777778 base units, and 1 gigameter equals 1000000000 base units, so dividing one by the other gives the direct point-to-gigameter factor of 3.527778e-13.
Simple example
1 pt × 3.527778e-13 = 3.527778e-13 Gm
1 point = 3.527778e-13 gigameters.
Real-world example
10 pt × 3.527778e-13 = 3.527778e-12 Gm
10 points = 3.527778e-12 gigameters.
