Latitude values indicate the angular distance between the Equator and points north or south of it on the surface of the Earth. ... Lines of longitude, called meridians, run perpendicular to lines ... Calculator for surface distance between two points – converts latitude and longitude to kilometers, miles, and nautical miles...

A line starting at the north pole, ... We work with a sphere whose radius is 3957 miles or 6367 kilometers -- the average of the equatorial radius and the polar radius. By making this simplification we will introduce errors of up to 12 miles in the distance between two points on opposite sides of the earth.

It is the shortest distance between two points on a sphere. ... Note the comparable great circle path approximation between the equator’s intersection with the Greenwich meridian (latitude 0° and longitude 0°) and the North Pole (latitude 90°, longitude undefined) is simply the latitude difference multiplied by 60nmi/°...

[167] What is a celestial pole? ... where l1 and b1 are the longitude and latitude of the first point, and l2 and b2 the longitude and latitude of the second point (with + or - for east or west longitude and north or south latitude). The result d is then the (shortest) angular distance between the two points across the sphere.
