The Prime Meridian runs through the London Borough of Greenwich, meaning it has a longitude of zero degrees. London is approx 51.5° north of the equator.
In summary: 51°32'N, 0°W
51, 32 N, 0, 5 W
Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.
All lines of longitude are equal. The longest line of latitude is the Equator.
longitude
The longitude lines cover the vertical side of the earth and the latitude lines cover the horizontal side. This gives you map coordination's.
51, 32 N, 0, 5 W
Lines of Latitude encircle the Earth horizontally, and are parallel to the Equator. Lines of Latitude are intercepted by Lines of Longitude. Lines of Longitude run vertically from the North Pole to the South Pole. The Prime Meridian is zero longitude and passes through the Greenwich Observatory, Greenwich, London, England.

The North/South lines on the geographic grid are named 'Lines of Longitude' or 'Meridians'. The 'Zero' line passes through Greenwich Observatory in London, England. This position was fixed historically, some 350 years ago, by Astronomers and navigators of the day, and has remained so to this day. The 180 degrees line of longitude passes through the Pacific Ocean, and for most of its course it is also the International Date Line.
Each 'meridian' is a line of constant longitude.
Latitude.
Lines of latitude encircle the Earth horizontally, parallel to the Equator. Lines of longitude run from pole to pole, with the Prime Meridian (zero longitude) passing through the Royal Observatory, Greenwich, London, England.
Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.
Latitude and longitude
The lines that intercept latitude lines are lines of longitude.
