About Converting Links to Micrometers
Link and Micrometer both measure length. Specifically: A surveyor's link is 1/100 of a chain, and micrometer is 0.000001 meter units.
Formula
micrometers = links × 201168
This factor comes from each unit's defined relationship to the category's base unit: 1 link equals 0.201168 base units, and 1 micrometer equals 0.000001 base units, so dividing one by the other gives the direct link-to-micrometer factor of 201168.
Simple example
1 li × 201168 = 201,168 um
1 link = 201,168 micrometers.
Real-world example
10 li × 201168 = 2,011,680 um
10 links = 2,011,680 micrometers.
