What is a chain (US survey)?

It is a traditional unit of length equal to 66 US survey feet, historically used in U.S. land surveying and subdivided into 100 links.

What distances are measured in gigameters?

Gigameters measure very large lengths such as interplanetary distances, spacecraft trajectories, and planetary separations.

Why convert from chain to gigameter?

To translate historical land survey measurements into large-scale scientific units suitable for fields like planetary science and aerospace engineering.

Limitations

The chain (US survey) is a small, legacy unit not suited for representing large distances without very small fractional values.
Gigameters are designed for vast distances, so conversions often yield results with extremely small decimals.
This tool does not account for precision beyond the provided conversion rate and is intended for general use.
Using chain to gigameter conversions for everyday distance measurements is uncommon and may be impractical.
