What Is This Tool?
This tool enables conversion between the Bohr radius, an atomic-scale unit of length used in quantum chemistry and physics, and the US survey mile, a unit commonly used in land surveying and mapping in the United States.
How to Use This Tool?
-
Enter the length value in Bohr radius units you wish to convert
-
Select Bohr radius as the source unit and US survey mile as the target unit
-
Click the convert button to obtain the equivalent length in miles
-
Review the results shown in miles for your analysis or application
Key Features
-
Converts length values from Bohr radius to US survey mile quickly and accurately
-
Useful for bridging atomic-scale and geodetic distance measurements
-
Provides practical examples for easy understanding
-
Supports interdisciplinary uses including quantum physics and surveying
Examples
-
10 Bohr radius equals approximately 3.2881484048501e-13 US survey miles
-
1,000 Bohr radius converts to about 3.2881484048501e-11 US survey miles
Common Use Cases
-
Quantum chemistry and atomic-structure calculations requiring unit conversion
-
Interdisciplinary research linking atomic-scale and terrestrial length units
-
Surveying and mapping where comparing quantum units with conventional land measures is needed
-
Education comparing vastly different scales of measurement in science
Tips & Best Practices
-
Always double-check entered values for accuracy due to extremely small conversion factors
-
Use the tool primarily for comparative or specialized academic applications rather than everyday measurements
-
Be aware of the practical limitations of small converted results in large-scale contexts
Limitations
-
Converted values are extremely small given the large difference in scale between Bohr radius and miles
-
Such minuscule results may be impractical for general measurement purposes
-
Numerical precision issues may arise due to the tiny conversion factor
Frequently Asked Questions
-
What is a Bohr radius used for?
-
The Bohr radius is primarily used in quantum chemistry, atomic-structure calculations, and computational physics to express interatomic distances compactly.
-
Why is the US survey mile still used?
-
The US survey mile is maintained for land surveys and legal descriptions to ensure consistency with historical cadastral and geodetic data in the United States.
-
Can I use this conversion for everyday measurements?
-
Due to the extremely small size of the Bohr radius compared to miles, converted values are usually too small and impractical for everyday use.
Key Terminology
-
Bohr radius
-
The atomic unit of length equal to about 5.29177210903×10⁻¹¹ metres, representing the most probable distance between the nucleus and electron in hydrogen.
-
US survey mile
-
A unit of length equal to exactly 5,280 US survey feet used in surveying and mapping, where one US survey foot equals 1,200/3,937 metres.
-
Cadastral surveys
-
Land surveys defining property boundaries and legal descriptions based on historical measurement units.
