Latitude and Longitude

When taking a look at a map, latitude lines run horizontally. Latitude lines are likewise referred to as parallels since they are parallel and are an equal far-off from each other. Each degree of latitude is roughly 69 miles (111 km) apart; there is a variation due to the fact that the earth is not an ideal sphere however an oblate ellipsoid (somewhat egg-shaped). To bear in mind latitude, envision them as the horizontal rungs of a ladder (“ladder-tude”). Degrees latitude are numbered from 0 ° to 90 ° north and south.

No degrees is the equator, the fictional line which divides our world into the northern and southern hemispheres. 90 ° north is the North Pole and 90 ° south is the South Pole.


The vertical longitude lines are also known as meridians. They converge at the poles and are widest at the equator (about 69 miles or 111 km apart). Zero degrees longitude is located at Greenwich, England (0°). The degrees continue 180° east and 180° west where they meet and form the International Date Line in the Pacific Ocean.

Greenwich, the site of the British Royal Greenwich Observatory, was established as the site of the prime meridian by an international conference in 1884.

How Latitude and Longitude Work Together

To precisely locate points on the earth’s surface, degrees longitude and latitude have been divided into minutes (‘) and seconds (“). There are 60 minutes in each degree. Each minute is divided into 60 seconds. Seconds can be further divided into tenths, hundredths, or even thousandths. For example, the U.S. Capitol is located at 38°53’23″N , 77°00’27″W (38 degrees, 53 minutes, and 23 seconds north of the equator and 77 degrees, no minutes and 27 seconds west of the meridian passing through Greenwich, England).
