What is a chain [ch] used for?

A chain is a traditional surveying length unit historically used in cadastral surveying, land measurement, and interpreting older engineering or property records.

When would I use terameter [Tm] as a unit?

Terameter is used to express very large distances, such as interplanetary distances and planetary orbits, in astronomy and planetary science.

Why convert from chains to terameters?

Converting chains to terameters helps translate historical land measurements into the very large distance units used in astronomy and planetary studies.
