What is a furlong (US survey)?

A furlong (US survey) is a historical unit of length used in U.S. land surveying, precisely defined as 660 US survey feet or about 201.1684 meters.

What does the Bohr radius represent?

The Bohr radius is the atomic unit of length corresponding to the most probable distance between the nucleus and electron in the hydrogen atom's ground state.

Why convert from furlong to Bohr radius?

This conversion helps bridge macroscopic land measurement scales with atomic-scale units, useful in quantum chemistry, physics, and metrology.

Comparing macroscopic survey distances with atomic-scale lengths in metrology.

Tips & Best Practices

Ensure input values use the correct unit to avoid conversion errors.
Use this conversion mainly for theoretical, scientific contexts rather than practical measurement.
Interpret results with care when bridging very different length scales.
Refer to current definitions when working with historical units to ensure consistency.

Limitations

The US survey furlong is a historical, non-SI unit with limited standardized modern use.
Bohr radius is specific to atomic-scale measurements and not practical for everyday lengths.
Conversion is mostly theoretical for linking large and atomic length scales.
Possible variations in exact unit definitions may affect precision.
