What Is This Tool?
This online unit converter transforms measurements from the historic surveying length unit link (li) into astronomical units (AU, UA), a standard for space distances. It enables users to relate terrestrial measurements to solar system scales.
How to Use This Tool?
-
Enter the value in links (li) you want to convert
-
Select astronomical unit (AU, UA) as the target unit
-
Click the convert button to see the equivalent measurement in astronomical units
Key Features
-
Converts length from link (li) to astronomical unit (AU, UA) with defined conversion rates
-
Browser-based, user-friendly interface for quick conversions
-
Supports analysis involving historical surveying and astronomical distance contexts
Examples
-
1000 links (li) is equal to 1.3447250222934e-9 astronomical units (AU, UA)
-
500 links (li) equals 6.723625111467e-10 astronomical units (AU, UA)
Common Use Cases
-
Interpreting and converting distances from old land measurement documents
-
Reconstructing historic property boundaries for archival research
-
Planning or analyzing space missions using consistent length units
-
Comparing terrestrial land measurements with celestial distance scales
Tips & Best Practices
-
Use scientific notation for displaying very small values after conversion
-
Consider the historical context when interpreting link measurements
-
Verify the purpose before conversion, as this tool suits niche interdisciplinary research
-
Cross-reference converted values with original documents for historical accuracy
Limitations
-
The link is an old unit with limited accuracy dependent on historical measurement quality
-
Astronomical units are extremely large compared to links, resulting in very small converted values
-
Conversions have limited everyday practical use and are mainly for specialized research
Frequently Asked Questions
-
What is a link (li) used for?
-
A link is a historic English unit of length used mainly in 18th and 19th century land surveying and cadastral records.
-
Why convert link to astronomical unit?
-
Converting link to astronomical unit helps relate terrestrial historical land measurements to vast celestial distances, useful in interdisciplinary studies involving history and space science.
-
What does one astronomical unit represent?
-
One astronomical unit is approximately the average distance from the Earth to the Sun and is defined as exactly 149,597,870,700 metres.
Key Terminology
-
Link (li)
-
A historic English length unit equal to 1/100 of Gunter's chain, mainly used in old land surveying.
-
Astronomical Unit (AU, UA)
-
A length unit defined as exactly 149,597,870,700 metres, commonly used to express distances within the Solar System.
-
Gunter's Chain
-
A historic surveying measuring device of which one link is 1/100 part.
