What Is This Tool?
This unit converter transforms length values from the Bohr radius, a quantum chemistry atomic unit, to the long cubit, an ancient measurement mainly used in archaeological and historical contexts.
How to Use This Tool?
-
Enter the length value in Bohr radius units into the input field.
-
Select the Bohr radius as the from-unit and long cubit as the to-unit.
-
Click convert to get the equivalent length expressed in long cubits.
Key Features
-
Converts length from Bohr radius (atomic scale) to long cubit (ancient length unit).
-
Based on established approximate conversion rate linking atomic units to historical units.
-
Useful for interdisciplinary studies combining physics, archaeology, and history.
-
Browser-based and straightforward to use without needing scientific knowledge.
-
Supports interpretation of atomic distances in familiar historical units.
Examples
-
Convert 10 Bohr radius to long cubits: result is 10 × 9.9208333145858e-11 long cubits.
-
Convert 1,000 Bohr radius to long cubits: result is 1,000 × 9.9208333145858e-11 long cubits.
Common Use Cases
-
Translating atomic-scale distances into historical length units for educational purposes.
-
Integrating computational physics data with archaeological measurements in long cubits.
-
Describing dimensions of ancient objects or inscriptions recorded with cubit units.
Tips & Best Practices
-
Understand that the long cubit's value varies historically, so interpret results as approximate.
-
Use the tool mainly for conceptual comparisons rather than precise physical measurements.
-
Combine this conversion with contextual historical knowledge for best interpretation.
Limitations
-
The long cubit's length varies by period and region, so conversions use an average value.
-
Bohr radius is an atomic scale unit resulting in extremely small decimal values when converted.
-
Practical use is limited; mainly suited for conceptual or interdisciplinary comparative studies.
Frequently Asked Questions
-
What is the Bohr radius used for?
-
The Bohr radius is used as an atomic unit of length in quantum chemistry, atomic-structure calculations, and computational physics.
-
Why convert Bohr radius to long cubit?
-
Converting to long cubit helps relate atomic distances to historical length measures for interdisciplinary studies in physics, archaeology, and history.
-
Is the long cubit length constant?
-
No, the long cubit's value varies by historical period and location, so the conversion is based on an approximate average.
Key Terminology
-
Bohr radius

Atomic length unit representing the most probable nucleus-electron distance in a hydrogen atom's ground state.
-
Long cubit
-
Ancient unit of length used in Egypt and the Near East, roughly equivalent to 52–57 cm, often called the royal cubit.
