What Is This Tool?
This converter allows you to translate length values from the classical electron radius, a subatomic unit used in physics, into the historic English surveying unit called the link (li). It supports applications in both scientific and historical measurement interpretations.
How to Use This Tool?
-
Enter the value in Electron radius (classical)
-
Select Electron radius (classical) as the input unit
-

Key Features
-
Converts Electron radius (classical) to Link [li] based on established conversion rates
-
Supports unit definitions from particle physics and historical surveying
-
Browser-based with easy input and output display
-
Provides exact conversion factor for accurate calculation
-
Useful for interpreting old land records and physics problems
Examples
-
1 Electron radius (classical) ≈ 1.4 × 10^-14 Link [li]
-
10 Electron radius (classical) ≈ 1.4 × 10^-13 Link [li]
Common Use Cases
-
Converting electron scattering lengths into historic land surveying units
-
Analyzing historical land measurement records with links
-
Supporting research in particle, plasma, and radiation physics
-
Interpreting cadastral documents containing legacy unit measurements
Tips & Best Practices
-
Double-check unit selections before conversion
-
Understand the scale difference between atomic units and land survey units
-
Use the tool primarily for interpretive or archival purposes
-
Consult historical context when working with links
-
Recognize the electron radius as a theoretical characteristic length
Limitations
-
Electron radius values correspond to subatomic scales, much smaller than links
-
Resulting converted values are extremely small and may lack practical meaning in land surveying
-
The link unit is obsolete and rarely used outside historical contexts
-
Significant scale differences limit precise or common scientific use
Frequently Asked Questions
-
What is the classical electron radius used for?
-
It is a derived length scale in physics used to characterize scattering lengths and normalize interaction strengths, especially in particle and radiation physics.
-
What is a link (li) unit?
-
The link is a historic English unit of length used mainly in the 18th and 19th centuries for land surveying, equal to 0.201168 meters.
-
Why convert Electron radius (classical) to Link [li]?
-
This conversion helps interpret extremely small scattering lengths in terms of a historic surveying unit, useful for archival and historical research.
Key Terminology
-
Electron radius (classical)
-
A derived subatomic length scale representing the distance where an electron's electrostatic self-energy equals its rest energy, used in scattering and physics calculations.
-
Link [li]
-
A historic English unit of length for land surveying equal to 1/100th of a Gunter's chain or about 0.201168 meters, mainly used in 18th and 19th century documents.
