What is the UK nautical mile (NM UK)?

The UK nautical mile, also known as the Admiralty nautical mile, is historically defined as exactly 6,080 feet or 1,853.184 metres, making it slightly longer than the international nautical mile.

What does atomic unit of length (a.u., b) refer to?

The atomic unit of length is the Bohr radius, representing the typical electron–proton separation in a hydrogen atom and used in atomic and molecular physics for simplifying quantum mechanical calculations.

Why convert nautical miles (UK) to atomic units of length?

This conversion is useful for theoretical and scientific research that connects macroscopic maritime distances with atomic-scale measurements, such as quantum chemistry modeling or atomic physics studies.

Converting and reconciling legacy nautical mile distances to SI or atomic scale for scientific research.
Comparing and restoring historic navigation instruments or datasets based on the UK definition.
Translating large maritime distances into atomic-scale units for modeling in computational quantum chemistry.

Tips & Best Practices

Double-check whether distances are in UK nautical miles versus international nautical miles to avoid confusion.
Remember that due to the scale difference, resulting values are extremely large numbers.
Use the results primarily for theoretical or research purposes rather than everyday measurements.
Be mindful of potential computational complexity when working with very large conversion factors.

Limitations

The UK nautical mile is a legacy unit slightly longer than the international nautical mile, requiring cautious comparison.
Extreme difference in scale between nautical miles and atomic units leads to very large values that may present computational challenges.
This conversion is uncommon in typical use and mostly relevant to specialized scientific and theoretical contexts.
