About Converting Links to Femtometers
Link and Femtometer both measure length. Specifically: A surveyor's link is 1/100 of a chain, and femtometer is 1e-15 meter units.
Formula
femtometers = links × 2.01168e+14
This factor comes from each unit's defined relationship to the category's base unit: 1 link equals 0.201168 base units, and 1 femtometer equals 1e-15 base units, so dividing one by the other gives the direct link-to-femtometer factor of 2.01168e+14.
Simple example
1 li × 2.01168e+14 = 2.01168e+14 fm
1 link = 2.01168e+14 femtometers.
Real-world example
10 li × 2.01168e+14 = 2.01168e+15 fm
10 links = 2.01168e+15 femtometers.
