What is a UK nautical mile (NM (UK))?

It is a historical unit defined as exactly 6,080 feet or 1,853.184 metres, slightly longer than the international nautical mile of 1,852 metres.

Why convert nautical miles (UK) to gigameters?

Converting helps interpret historical maritime distances in modern SI units, useful for planetary science and astronomical distance comparisons.

Is this conversion precise for navigation today?

No, since the UK nautical mile is a legacy unit and gigameters represent very large scales, this conversion is better for scientific and historical analysis than everyday maritime navigation.
