What Is This Tool?
This tool converts the historic English unit of length called the Link (li), typically used in surveying, into the classical electron radius, a fundamental length scale from physics representing electromagnetic interactions. It enables bridging historic measurement units with scientific constants.
How to Use This Tool?
-
Enter the value in Link (li) you want to convert.
-
Select Electron radius (classical) as the target unit.
-
Click convert to get the equivalent length in classical electron radii.
-
Use provided examples to understand the conversion scale.
Key Features
-
Converts Link (li), a surveying unit equal to 0.201168 metres, into the classical electron radius.
-
Provides large-scale conversion for interdisciplinary use between historic land measurement and atomic physics.
-
Includes formula and examples for straightforward unit translation.
-
Accessible online tool suitable for researchers in land surveying history and physics disciplines.
Examples
-
1 Link (li) equals 71,388,295,819,914 classical electron radii.
-
0.5 Link (li) equals 35,694,147,909,957 classical electron radii.
Common Use Cases
-
Interpreting historic surveying distances recorded in Link (li) units.
-
Relating land measurement units to fundamental physics scales in research.
-
Applying conversions in studies combining historical cadastral data with electromagnetic theory.
-
Normalizing scattering lengths in atomic, plasma, and astrophysical physics contexts.
Tips & Best Practices
-
Ensure the input value is from historic or archival sources when using Link (li).
-
Use the conversion primarily for conceptual or comparative scale purposes.
-
Cross-reference with modern measurement units for practical applications.
-
Understand the classical electron radius is a theoretical length, not a physical size.
Limitations
-
Link (li) is an obsolete unit mainly relevant to historical data.
-
Classical electron radius is a theoretical construct, not representing actual electron size.
-
Large conversion magnitude limits direct practical uses outside specialized research.
-
This conversion serves more conceptual and interdisciplinary study aims.
Frequently Asked Questions
