Longitude
Conversely, longitude lines can be expressed by dividing Earth into vertical segments totalling 360 degrees. Starting at the
Prime Meridian (which is The Royal Observatory in Greenwich, England), or zero degrees Longitude, lines are drawn in 10-
degree increments 180 degrees to the West and 180 degrees to the East. If your location is on the western hemisphere, you
are at a West Longitude.
Additionally, to narrow down your location further, each 10-degree segment is divided into 60 smaller segments called
minutes and, still further, each minute is divided into 60 segments called seconds.
To express this in coordinates, the city of Los Angeles is located at 34° (degrees) 03’ (minutes) and 08 (seconds) North of
the Equator, and 118° (degrees) 14’ (minutes) and 42 (seconds) West of the Prime Meridian.
