What Is This Tool?
This tool facilitates the conversion of length values from atomic units of length, based on the Bohr radius, to the historic English unit known as the link, commonly used in old land surveying. It helps bridge atomic-scale distance measurements with historical surveying units.
How to Use This Tool?
-
Enter the length value expressed in atomic units of length (a.u. of length [a.u., b])
-
Choose the target unit as link [li]
-
Click convert to see the length expressed in links
-
Use the result to compare or interpret measurements across different unit systems
Key Features
-
Converts atomic unit lengths (Bohr radius) to the historic link unit
-
Supports conversions linked to both atomic physics and historical surveying
-
Provides precise conversion factors based on defined unit relationships
-
Suitable for application in quantum chemistry and cadastral analysis contexts
Examples
-
1 a.u. of length equals approximately 2.6305239849281e-10 links
-
10 a.u. of length converts to about 2.6305239849281e-9 links
Common Use Cases
-
Reporting electron orbital sizes and radial probabilities in atomic and molecular physics through atomic units
-
Interpreting distances from historic surveying documents expressed in links
-
Translating quantum chemical interatomic distances into historic land measurement units for cadastral research
-
Reconstructing property boundaries using both atomic-scale and archival unit systems
Tips & Best Practices
-
Ensure numeric values are entered accurately to maintain conversion precision
-
Use this conversion primarily for archival or research purposes combining atomic physics and surveying history
-
Be aware of the significant scale difference between atomic units and links which leads to small decimal values
-
Cross-check converted values especially when applying to historical land data analysis
Limitations
-
Conversion results in very small decimal numbers due to the atomic unit’s extremely small scale compared to the link
-
Link is a historic unit rarely employed in modern measurements, limiting practical application
-
Not suitable for typical surveying tasks where larger scale units are preferred
Frequently Asked Questions
-
What is the atomic unit of length used here?
-
It is the Bohr radius, representing the typical distance between an electron and proton in hydrogen, used in atomic physics.
-
Why convert from atomic units to the link?
-
To translate atomic-scale distance measurements into historic surveying units for research involving old cadastral records.
-
Is the link unit still used today?
-
No, the link is primarily a historical unit once used in land surveying and is not common in modern measurement.
Key Terminology
-
Atomic unit of length (a.u.)
-
The Bohr radius, a fundamental length scale in atomic physics representing electron-proton separation in hydrogen.
-
Link (li)
-
A historic English unit of length equal to 1/100 of Gunter's chain, used mostly in 18th and 19th-century surveying.
-
Bohr radius
-
The characteristic distance scale in atomic physics roughly equal to 5.29177210903×10⁻¹¹ meters.
