Moving along the meridian of the Earth by one nautical mile (1852 m) exactly corresponds to a change in geographical latitude

Moving along the meridian of the Earth by one nautical mile (1852 m) exactly corresponds to a change in geographical latitude by 1 /. Based on this, find the diameter of the Earth.

Let R be the radius of the Earth. The distance along the meridian from pole to pole is equal to nR. It is in miles equal to 180 • 60 miles
= (180 * 60 * 1852) / n = 6367 km
