What Is This Tool?
This converter allows you to transform length values measured in Bohr radius, an atomic unit of length, into feet based on the U.S. survey foot system. It is useful for translating nano-scale atomic measurements into traditional surveying units.
How to Use This Tool?
-
Enter the length value in Bohr radius units.
-
Select Bohr radius as the input unit and foot (US survey) as the output unit.
-
Initiate the conversion to get the equivalent value in US survey feet.
Key Features
-
Simple conversion between Bohr radius and foot (US survey) units.
-
Based on exact defined conversion rates between units.
-
Useful for bridging atomic-scale and geospatial length measurements.
Examples
-
5 Bohr radius is approximately 8.6807117888e-10 foot (US survey).
-
1e10 Bohr radius converts to around 1.73614235776 foot (US survey).
Common Use Cases
-
Quantum chemistry and atomic-structure calculations requiring unit translation.
-
Interfacing atomic-scale data with legacy land survey and construction records.
-
Translating nano-scale lengths into geodetic and engineering measurements.
Tips & Best Practices
-
Ensure the units selected match the measurement context before conversion.
-
Use this conversion mainly when linking atomic-scale data with traditional surveying data.
-
Be cautious with very small converted values to avoid misunderstanding scale.
Limitations
-
Bohr radius units represent atomic distances vastly smaller than survey feet.
-
Very small scaling factors mean numerical precision must be handled carefully.
-
The US survey foot is a legacy unit that may slightly differ from the international foot.
Frequently Asked Questions
-
What is a Bohr radius?
-
The Bohr radius is the atomic unit of length representing the typical distance between the nucleus and electron in a hydrogen atom, defined exactly by physical constants.
-
Why use the US survey foot for conversion?
-
The US survey foot is historically used in land surveying and mapping in the United States, making it relevant for translating atomic measurements into legacy geospatial units.
-
Is this conversion practical for everyday use?
-
Due to the atomic scale of the Bohr radius and the significantly larger survey foot, this conversion is generally applied in specialized scientific and engineering fields rather than routine measurements.
Key Terminology
-
Bohr radius
-
An atomic unit of length equal to the most probable distance between the nucleus and electron in hydrogen's ground state.
-
Foot (US survey)
-
A unit of length used historically in US land surveying, defined exactly as 1200/3937 meters.
-
Conversion rate
-
The exact factor used to translate a measurement from one unit to another, here 1 Bohr radius equals approximately 1.7361423577609e-10 foot (US survey).
