About Converting Megameters to Chains
Megameter and Chain both measure length. Specifically: Megameter is 1000000 meter units, and a surveyor's chain is 66 feet.
Formula
chains = megameters × 49709.695379
This factor comes from each unit's defined relationship to the category's base unit: 1 megameter equals 1000000 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct megameter-to-chain factor of 49709.695379.
Simple example
1 Mm × 49709.69538 = 49,709.69538 ch
1 megameter = 49,709.69538 chains.
Real-world example
10 Mm × 49709.69538 = 497,096.9538 ch
10 megameters = 497,096.9538 chains.
