What is the Earth’s equatorial radius used in this conversion?

It is the straight-line distance from the Earth's center to the equator along the equatorial plane, standardized at 6,378.137 kilometers based on the WGS84 reference ellipsoid.

How does the UK nautical mile differ from the international nautical mile?

The UK nautical mile (NM UK) is defined as exactly 6,080 feet or 1,853.184 meters, making it slightly longer than the international nautical mile of exactly 1,852 meters.

Why might I need to convert Earth's equatorial radius to UK nautical miles?

This conversion helps relate geodetic and aerospace data to legacy maritime distances from UK Admiralty charts and historic navigation logs for accurate interpretation.
