About Converting Links to Chains
Link and Chain both measure length. Specifically: A surveyor's link is 1/100 of a chain, and a surveyor's chain is 66 feet.
Formula
chains = links × 0.01
This factor comes from each unit's defined relationship to the category's base unit: 1 link equals 0.201168 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct link-to-chain factor of 0.01.
Simple example
1 li × 0.01 = 0.01 ch
1 link = 0.01 chains.
Real-world example
10 li × 0.01 = 0.1 ch
10 links = 0.1 chains.
Conversion table
| Link (li) | Chain (ch) |

Reverse conversion: Chain to Link
0.01 ch × 100 = 1 li
0.01 chains = 1 link.
links = chains × 100

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