About Converting Exameters to Chains
Exameter and Chain both measure length. Specifically: Exameter is 1000000000000000000 meter units, and a surveyor's chain is 66 feet.
Formula
chains = exameters × 4.97097e+16
This factor comes from each unit's defined relationship to the category's base unit: 1 exameter equals 1e+18 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct exameter-to-chain factor of 4.97097e+16.
Simple example
1 Em × 4.97097e+16 = 4.97097e+16 ch
1 exameter = 4.97097e+16 chains.
Real-world example
10 Em × 4.97097e+16 = 4.97097e+17 ch
10 exameters = 4.97097e+17 chains.
