About Converting Petameters to Chains
Petameter and Chain both measure length. Specifically: Petameter is 1000000000000000 meter units, and a surveyor's chain is 66 feet.
Formula
chains = petameters × 4.97097e+13
This factor comes from each unit's defined relationship to the category's base unit: 1 petameter equals 1e+15 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct petameter-to-chain factor of 4.97097e+13.
Simple example
1 Pm × 4.97097e+13 = 4.97097e+13 ch
1 petameter = 4.97097e+13 chains.
Real-world example
10 Pm × 4.97097e+13 = 4.97097e+14 ch
10 petameters = 4.97097e+14 chains.
