Latitude exact relationship of parallels and meridians with horizontal and vertical: both are complicated curves. On the sphere the normal passes through the centre and the latitude () is therefore equal to the angle subtended at the centre by the meridian arc from the equator to the point concerned. If the meridian distance is denoted by then where denotes the mean radius of the Earth. is equal to . No higher accuracy is appropriate for since higher-precision results necessitate an ellipsoid model. With this value for the meridian length of 1 degree of latitude on the sphere is (60.0 nautical miles).
1987 (What the Fuck Is Going On?) follow – "We're not The Monkees, I don't even "like" The Monkees!" – before it gets interrupted by an original a cappella vocal line that later became The KLF's "Justified and Ancient" – "We're justified/And we're ancient ...
