About Converting Terameters to Chains
Terameter and Chain both measure length. Specifically: Terameter is 1000000000000 meter units, and a surveyor's chain is 66 feet.
Formula
chains = terameters × 49709695379
This factor comes from each unit's defined relationship to the category's base unit: 1 terameter equals 1e+12 base units, and 1 chain equals 20.1168 base units, so dividing one by the other gives the direct terameter-to-chain factor of 49709695379.
Simple example
1 Tm × 49709695380 = 49,709,695,380 ch
1 terameter = 49,709,695,380 chains.
Real-world example
10 Tm × 49709695380 = 497,096,953,800 ch
10 terameters = 497,096,953,800 chains.

Reverse conversion: Chain to Terameter
1 ch × 2.01168e-11 = 2.01168e-11 Tm
1 chain = 2.01168e-11 terameters.
terameters = chains × 2.01168e-11

How do I convert chain back to terameter?
Use the reverse factor: 1 chain equals 2.01168e-11 terameters. You can also use the swap control in the converter above to flip the direction instantly.
What is a terameter?
Terameter (Tm) is a unit of length.
What is a chain?
Chain (ch) is a unit of length.
Is the terameter to chain conversion exact?
Yes. Both terameter and chain are defined by fixed standards rather than physical artifacts, so the factor of 49709695380 used above is exact to as many digits as you choose to display.
