What do lines of latitude measure?

Lines of latitude are imaginary reference lines that describe how far north or south a location on the Earth is from the Equator. Latitude is measured in degrees, minutes, and seconds north or south with the Equator valued at zero degrees and the north and south poles as 90 degrees north and south, respectively. Latitude combined with longitude gives a coordinate for any location on the Earth.
