It is the opposite meridian to the 0degree meridian or Prime meridian , as it cuts the earth into two equal halves named eastern and western hemispheres. These
east and west hemispheres are limited to the 180degree meridian or international date line , so it is not denoted as east or west meridian.
The distance from the prime meridian is usually measured in degrees of longitude. The distance east or west of the prime meridian is referred to as "longitude."
The prime meridian is located at Greenwich, England in the district of South East London and is denoted as longitude 0 degrees. The prime passes through Europe, Africa, and Antarctica.
Meridians east of the prime meridian are labeled with the letter E, which stands for east. The prime meridian itself is labeled as 0° longitude, and meridians to the east are assigned increasing positive longitude values.
Longitude !
The distance east or west from the Prime Meridian is measured in degrees, with 360 degrees in a full circle representing the Earth's circumference. The Prime Meridian itself is set at 0 degrees longitude, so any location east of it will have a positive longitude value, while any location west of it will have a negative longitude value.
Longitude: 57º 33´East of Greenwich Meridian.
It is fifteen degrees East. (15 degrees East of the Prime Meridian. The Prime Meridian being zero longitude).
Longitude lines. They are also called meridians.
prime meridian
Yes.
The meridian of 180° longitude (both ways, east or west)
All meridians of longitude have the same nominal length. However, at any given longitude, the meridian of 180° East longitude is the one farthest from the Prime Meridian. Perhaps that's what you had in mind.
