What Is This Tool?
This converter allows you to transform measurements from the atomic unit of length, based on the Bohr radius, into the US survey link, a historical surveying unit. It is designed to bridge the scale gap between atomic physics distances and legacy land measurement systems.
How to Use This Tool?
-
Enter the length value in atomic units [a.u., b]
-
Select the desired output unit as link (US survey) [li]
-
Click convert to obtain the equivalent measurement
-
Use converted values to compare or reconcile different datasets
Key Features
-
Converts atomic unit of length to US survey link accurately
-
Supports applications in quantum physics and land surveying
-
Browser-based tool with simple interface
-
Facilitates reconciliation of atomic scale data with historical survey units
Examples
-
1 a.u. of length equals 2.6305187238801×10⁻¹⁰ li
-
10 a.u. of length equals 2.6305187238801×10⁻⁹ li
Common Use Cases
-
Reporting electron orbital sizes and radial probability distributions in atomic and molecular physics
-
Specifying atomic geometries in quantum-chemistry calculations such as Hartree–Fock and DFT
-
Converting distances from quantum mechanical scales to historic US land survey records for cadastral mapping
-
Reconciling modern measurements with older US survey plats and deeds in civil engineering projects
Tips & Best Practices
-
Understand the distinct scale differences between the units before converting
-
Use this conversion primarily for theoretical or historical data integration
-
Double-check unit selections to ensure appropriate context for results
-
Leverage the tool to assist in bridging atomic-scale research with land survey documentation
Limitations
-
Atomic length units and survey links differ by vast magnitudes, limiting practical use
-
Conversion is mainly useful for theory or reconciling legacy and atomic datasets rather than routine measurements
-
Not intended for direct physical measurement conversion in everyday scenarios
Frequently Asked Questions
-
What is the atomic unit of length?
-
It is the Bohr radius, representing the average electron-proton separation in hydrogen, used in atomic physics to simplify equations.
-
What is a US survey link?
-
A US survey link is a historical land measurement equal to 1/100 of a Gunter's chain, approximately 0.201168 meters long, used in cadastral records.
-
Why convert atomic units to US survey links?
-
To translate atomic-scale quantum distances into units relevant for historical land survey data comparison or record reconciliation.
