A meridian describes an arc connecting the north and south poles (a single line of longitude). As such, a meridian will be 180 degrees.
Longitudes west of the prime meridian are given either as "40 degrees W" or "-40 degrees", with degrees represented by the "o" degree symbol.
The Prime Meridian of the world lies at 0˚ longitude.
The Prime Meridian marks the zero degree line of longitude. The Equator marks the line for zero degrees latitude.
It depends on the connotation of Prime Meridian. Although there are a number of meridians defined as prime meridians, the Greenwich Meridian was established as the international prime meridian in 1884 and is at 0 degrees longitude. The opposite is 180 degrees longitude. Vietnam is located between 100 and 110 degrees east longitude and between 0 and 25 degrees north latitude. To locate Vietnam using west longitudinal reference it would be between 250 and 260 degrees west longitude. Since the distance from the prime latitude to Vietnam is shorter in the eastward direction than the westward direction it would be considered east of prime meridian.
If you mean the longitude of the equator, it is 180 degrees east to west longitude.If you mean the intersection of the equator and Prime Meridian, it is the Gulf of Guinea.
Mexico City is 99.133333 degrees west of the Prime Meridian
The Greenwhich meridian also Prime Meridian is 0 degrees longitude and International Date Line roughly follows the 180° longitude or antimeridian. The antimeridian is the meridian which is 180° east or west of the Prime Meridian.
Shanghai, China is approximately 121 degrees east of the Prime Meridian, which is the internationally recognized marker of 0 degrees longitude.
The prime meridian (designated as zero) runs from pole to pole, passing through the Greenwich Observatory, London, England. Lines of longitude to the east of the prime meridian are so many degrees east, and to the west of the Prime Meridian are so many degrees west.
!80 degrees east of Greenwich and then one crosses over to West Longitude
The Prime Meridian is defined as the origin of longitude. The longitude of every point on it is zero.
There are 180-meridians in the eastern hemisphere. The meridian through Greenwich, England, also called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth is 180-degrees.
The Prime Meridian is at zero degrees longitude and every possible latitude.
