About Converting Chains to Links
Chain and Link both measure length. Specifically: A surveyor's chain is 66 feet, and a surveyor's link is 1/100 of a chain.
Formula
links = chains × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 chain equals 20.1168 base units, and 1 link equals 0.201168 base units, so dividing one by the other gives the direct chain-to-link factor of 100.
Simple example
1 ch × 100 = 100 li
1 chain = 100 links.
Real-world example
10 ch × 100 = 1,000 li
10 chains = 1,000 links.

Frequently asked questions
How many links are in 1 chain?
1 chain equals 100 links, using the exact defined conversion factor rather than an estimate.
How do I convert chain to link?
Multiply the chain value by 100. The converter above does this instantly to whatever precision you set.
How do I convert link back to chain?
Use the reverse factor: 1 link equals 0.01 chains. You can also use the swap control in the converter above to flip the direction instantly.
What is a chain?
Chain (ch) is a unit of length.
What is a link?
Link (li) is a unit of length.
Is the chain to link conversion exact?
Yes. Both chain and link are defined by fixed standards rather than physical artifacts, so the factor of 100 used above is exact to as many digits as you choose to display.
