What Is This Tool?

This converter allows you to change length values from the Bohr radius, an atomic unit used in quantum physics, to the perch, an old surveying measurement. It helps translate between microscopic atomic distances and traditional land measurement units.

How to Use This Tool?

  • Enter the length value in Bohr radius units.
  • Select Bohr radius as the input unit and perch as the output unit.
  • Click the convert button to see the result in perch.
  • Use the results to interpret or compare different length scales.

Key Features

  • Converts length from Bohr radius (atomic units) to perch (historical unit).
  • Useful for bridging quantum physics scales with historical surveying data.
  • Browser-based tool requiring no installation.
  • Handles very small conversion factors accurately.

Examples

  • 10 Bohr radius = 1.0522095939712e-10 perch
  • 1,000,000 Bohr radius = 1.0522095939712e-5 perch

Common Use Cases

  • Quantum chemistry and atomic-structure calculations using atomic units.
  • Interpreting and converting dimensions in historical property deeds.
  • Translating old surveying records or maps into modern units.
  • Research involving both atomic physics and historical land measurement.

Tips & Best Practices

  • Double-check unit selections before converting.
  • Use this tool primarily for research or archival data interpretation.
  • Be aware of the very small conversion factor due to the scale difference.
  • Consult historical references when working with cadastral or estate documents.

Limitations

  • The perch is largely obsolete and rarely used in modern measurement.
  • The Bohr radius is much smaller than the perch, causing very small output values.
  • Conversions may face rounding errors from the scale discrepancy.
  • Not practical for everyday length measurements outside specialized fields.

Frequently Asked Questions

What is a Bohr radius?
The Bohr radius 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 perch in measurement terms?
A perch is a historical unit of length equal to 16.5 feet or 5.0292 metres, once widely used in surveying and land measurement.

Why convert from Bohr radius to perch?
Converting helps connect atomic-scale distances in physics with traditional land measurement units, useful in research intersecting quantum physics and historical cadastral data.

Key Terminology

Bohr radius
An atomic unit of length roughly equal to 5.29177210903×10⁻¹¹ metres; represents the typical distance between the nucleus and electron in hydrogen's ground state.
Perch
A historical length unit equal to 16.5 feet (5.0292 metres), used mainly in surveying and land measurement but largely obsolete today.
Atomic unit
A system of natural units convenient for atomic physics representing fundamental physical quantities.
