Why are there 360? longitudes and 181? latitudes?

Answers (1)

Longitude lines runs from North to south pole means a complete circles and hence covers 360 degrees and that is why there are 360 longitudes. 

Latitudes tells you how far is the point from equator and hence is denoted by positive value when towards North pole and negative when towards south pole.Each section from equator to pole is 90 degrees and two poles have 2 quarters of circle/globe hence 90X2 180 lattitudes. adding the Equator it becomes 181 latitudes.
