I thought it was latitude but could be longitude, but I do remember that
the diameter of the earth at the equator in in knots is equal to 360 X 60.

A Knot is a unit of speed, not distance, and the distance you are

The circumference of the earth at the equator is approximately 360 x
60 nautical miles.
