What is a link (US survey) unit?

It is a historic small length unit for land surveying, equal to 1/100 of a Gunter's chain or about 0.66 US survey feet.

What does Earth's distance from the Sun represent?

It is the average distance between Earth and the Sun, defined exactly as 149,597,870,700 meters, and known as the astronomical unit (AU).

Why convert from a small survey unit to Earth's distance from the Sun?

To relate land surveying measurements to astronomical scales for educational, scientific comparison, or research purposes.

What Is This Tool?

This tool allows you to convert length values from the historical US survey link to Earth's average distance from the Sun, known as the astronomical unit (AU). It bridges small-scale land surveying units with large astronomical distances.

How to Use This Tool?

Enter the length value in link (US survey) units that you wish to convert.
Select the unit 'link (US survey) [li]' as the input unit.
Choose 'Earth's distance from Sun' as the output unit.
Initiate the conversion to view the equivalent value in astronomical units.
Use the results for comparative analysis or educational explanations.

Key Features

Converts link (US survey) [li] units to Earth's distance from the Sun (AU).
Uses an exact conversion rate based on established definitions of both units.
Supports applications in land surveying history and astronomy education.
Browser-based and easy to use without installation.
Offers quick and accurate conversion for scientific and educational contexts.

Examples

1000 links (US survey) [li] equals approximately 1.3447085717701e-9 Earth’s distance from Sun.
500000 links (US survey) [li] equals approximately 6.7235428588505e-7 Earth’s distance from Sun.

Common Use Cases

Interpreting and converting historic US land survey distances in legacy records.
Mapping cadastral boundaries with conversions to large-scale astronomical units.
Reconciling modern engineering measurements with old survey data.
Educational demonstrations relating terrestrial surveys to solar system scales.
Supporting astrophysics and aerospace planning by understanding unit conversions.

Tips & Best Practices

Enter precise values for accurate conversions between units.
Use this converter mainly for theoretical, educational, or research comparisons.
Keep in mind the link is obsolete for current surveying and the AU varies slightly yearly.
Check multiple conversion results when working with historic or scientific data for confirmation.

Limitations

The extremely small conversion factor means values can be insignificant for direct practical use.
The US survey link is an obsolete unit and rarely used in modern surveying.
Earth-Sun distance fluctuates between perihelion and aphelion affecting precise scaling.
Conversion serves mostly theoretical or educational goals rather than applied measurement.
