What is the UK nautical mile?

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.

Why convert UK nautical miles to hectometers?

Converting UK nautical miles to hectometers allows users to translate historical maritime distances into metric units useful for mapping, surveying, and legal contexts.

Is the hectometer commonly used?

The hectometer is an SI unit equal to 100 metres, used mainly for topographic mapping and land measurement but is less common in everyday distance measurement.
