What Is This Tool?
This converter changes length values from gigameters, an SI unit describing extremely large distances, into links (US survey), a traditional land surveying unit once used in the United States. It is designed for use in astronomy, planetary science, and cadastral mapping.
How to Use This Tool?
-
Enter the length value in gigameters.
-
Select the source unit as gigameter [Gm].
-
Choose the target unit link (US survey) [li].
-
Click convert to view the length in links.
Key Features
-
Converts very large distance units (gigameter) to small historic surveying units (link).
-
Supports applications in planetary science and legacy land survey interpretation.
-
Easy to use for bridging modern astronomical data with historic US land measurement units.
Examples
-
2 gigameters equals approximately 9,941,919,191.9192 links (US survey).
-
0.5 gigameter converts to about 2,485,479,797.9798 links (US survey).
Common Use Cases
-
Translating astronomical distances into units for historic US land survey records.
-
Reconciling planetary or spacecraft measurements with legacy cadastral data.
-
Supporting civil engineering projects requiring correlation between modern and historic units.
Tips & Best Practices
-
Use this converter when working with legacy US survey data alongside modern scientific measurements.
-
Be cautious of unit differences such as US survey feet versus international feet when interpreting results.
-
Employ this tool primarily for niche or historical land measurement contexts rather than precise modern calculations.
Limitations
-
The link (US survey) unit is outdated and not suitable for modern scientific precision at gigameter scales.
-
Converting large distances may introduce rounding or unit system discrepancies.
-
This tool serves mostly specialized fields involving legacy land surveys and planetary scale data.
Frequently Asked Questions
-
What is a gigameter used for?
-
A gigameter measures very large distances such as those in astronomy and planetary science, like distances within the Solar System.
-
Why convert gigameters to US survey links?
-
Converting to links helps reconcile modern astronomical measurements with historic US land survey units used in legal and cadastral contexts.
-
Is the link (US survey) commonly used today?
-
No, it is mostly a historical unit used in older survey records and cadastral mapping in the United States.
Key Terminology
-
Gigameter [Gm]
-
An SI derived unit of length equal to one billion meters, used for very large distances like those in planetary science.
-
Link (US survey) [li]
-
A historical length unit equal to 1/100 of a Gunter's chain, used in US land surveying and cadastral records.
