About Converting Chains to Hectometers
Chain and Hectometer both measure length. Specifically: A surveyor's chain is 66 feet, and hectometer is 100 meter units.
Formula
hectometers = chains × 0.201168
This factor comes from each unit's defined relationship to the category's base unit: 1 chain equals 20.1168 base units, and 1 hectometer equals 100 base units, so dividing one by the other gives the direct chain-to-hectometer factor of 0.201168.
Simple example
1 ch × 0.201168 = 0.201168 hm
1 chain = 0.201168 hectometers.
Real-world example
10 ch × 0.201168 = 2.01168 hm
10 chains = 2.01168 hectometers.

Frequently asked questions
How many hectometers are in 1 chain?
1 chain equals 0.201168 hectometers, using the exact defined conversion factor rather than an estimate.
How do I convert chain to hectometer?
Multiply the chain value by 0.201168. The converter above does this instantly to whatever precision you set.
How do I convert hectometer back to chain?
Use the reverse factor: 1 hectometer equals 4.970969538 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 hectometer?
Hectometer (hm) is a unit of length.
Is the chain to hectometer conversion exact?
Yes. Both chain and hectometer are defined by fixed standards rather than physical artifacts, so the factor of 0.201168 used above is exact to as many digits as you choose to display.
