What Is This Tool?
This converter allows you to change measurements from the Bohr radius, an atomic unit used in quantum chemistry and physics, to the barleycorn, a traditional British unit of length with historical significance.
How to Use This Tool?
-
Enter the measurement in Bohr radius (b, a.u.) into the input field.
-
Select barleycorn as the target unit for conversion.
-
Click the convert button to see the equivalent length in barleycorn.
-
Review the result and use it for interpretation or further work.

Examples
-
10 Bohr radius equals approximately 6.250124988189e-8 barleycorn.
-
1,000,000 Bohr radius converts to about 0.006250124988189 barleycorn.
Common Use Cases
-
Bridging atomic scale measurements with traditional British length units in research.
-
Interpreting scientific data within historical or pre-metric British measurement frameworks.
-
Applications in quantum chemistry, computational physics, and spectroscopy.
-
Analysing historical documents, tailoring patterns, and British shoe sizing.
Tips & Best Practices
-
Understand the scale difference between Bohr radius and barleycorn to avoid confusion.
-
Use the tool primarily for specialized contexts combining atomic and historic measurements.
-
Double-check conversions when applying results in practical or historical settings.
-
Consider limitations due to unit scale differences and rounding.
Limitations
-
The Bohr radius is extremely small compared to the barleycorn, making many conversions uncommon.
-
Barleycorn is largely obsolete outside niche traditional British applications.
-
Precision may be lost due to the difference in unit scales and rounding issues.
Frequently Asked Questions
-
What is a Bohr radius?
-
It is the atomic unit of length representing the most probable distance between the nucleus and electron in a hydrogen atom's ground state.
-
What is a barleycorn?
-
A barleycorn is a historic British length unit equal to one third of an inch, originally based on the length of a grain of barley.
-
Why convert between Bohr radius and barleycorn?
-
To relate atomic-scale scientific measurements to traditional British units, especially in cross-disciplinary and historical contexts.
Key Terminology
