About Converting Links to Petameters
Link and Petameter both measure length. Specifically: A surveyor's link is 1/100 of a chain, and petameter is 1000000000000000 meter units.
Formula
petameters = links × 2.01168e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 link equals 0.201168 base units, and 1 petameter equals 1e+15 base units, so dividing one by the other gives the direct link-to-petameter factor of 2.01168e-16.
Simple example
1 li × 2.01168e-16 = 2.01168e-16 Pm
1 link = 2.01168e-16 petameters.
Real-world example
10 li × 2.01168e-16 = 2.01168e-15 Pm
10 links = 2.01168e-15 petameters.
