About Converting Hectometers to Chains
Hectometer and Chain both measure length. Specifically: Hectometer is 100 meter units, and a surveyor's chain is 66 feet.
Formula
chains = hectometers × 4.9709695379
This factor comes from each unit's defined relationship to the category's base unit: 1 hectometer equals 100 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct hectometer-to-chain factor of 4.9709695379.
Simple example
1 hm × 4.970969538 = 4.970969538 ch
1 hectometer = 4.970969538 chains.
Real-world example
10 hm × 4.970969538 = 49.70969538 ch
10 hectometers = 49.70969538 chains.
