A fathom is a traditional English length unit equal to 6 feet (1.8288 meters), historically used to measure water depth and lengths of ropes or cables in maritime contexts.

How is the UK nautical mile defined?

The UK nautical mile, also known as the Admiralty nautical mile, is exactly 6,080 feet or 1,853.184 meters, slightly longer than the international nautical mile.

When should I use this converter?

This converter is useful for interpreting maritime charts, logs, and historical records that use fathoms and the UK nautical mile, particularly in UK naval or maritime heritage contexts.

Tips & Best Practices

Verify which nautical mile standard is used when working with nautical distances, as the UK nautical mile differs slightly from the international standard.
Use this converter primarily for traditional maritime contexts and historical document interpretation.
Be cautious when applying fathom measurements as they traditionally indicate depth or rope length rather than horizontal distances.

Limitations

The UK nautical mile differs slightly from the international nautical mile, so conversions should consider the specific standard applied.
Fathoms are typically depth or rope length units and may not always precisely represent distance measurements without proper context.
