Longitude (/ ˈlɒndʒɪtjuːd /, AU and UK also / ˈlɒŋɡɪ -/) [1][2] is a geographic coordinate that specifies the east – west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ).
Longitude is a measurement of location east or west of the prime meridian at Greenwich, London, England, the specially designated imaginary north-south line that passes through both geographic poles and Greenwich. Longitude is measured 180° both east and west of the prime meridian.
Oct 19, 2023 · Longitude is measured by imaginary lines that run around Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arc degree of longitude. The distance around Earth measures 360 degrees.
Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west. Longitude is measured in degrees, minutes, and seconds.

Longitude is measured 180° from both east as well as west of the prime meridian. Meridians are plotted and also drawn from one pole to another pole where they meet. How many latitudes and longitudes are there. There are a total of 181 latitudes, ninety north, ninety south, and one is the equator.
The Prime Meridian is set as 0° longitude and it divides the Earth into the Eastern and the Western Hemispheres. All the other longitudes are measured and named after the angle they make with respect to the center of the Earth from the intersection of the meridian and the equator.
Longitude is measured in degrees (°) and ranges from -180° (west) to +180° (east). Think of the geographic coordinate system dividing the Earth into a grid, with longitude representing east-west coordinates, and latitude representing north-south coordinates.
Jun 18, 2022 · Longitude (λ or lambda) specifies the east-west position of a point on the Earth’s surface. Each line of longitude runs from pole to pole and is called a meridian. The Prime Meridian passes near the Royal Observatory in Greenwich, England and has a defined value of 0°.
Apr 9, 2019 · Today, longitude is more accurately measured with atomic clocks and satellites. The Earth is still divided equally into 360° of longitude with 180° being east of the Prime Meridian and 180° west. Longitudinal coordinates are divided into degrees, minutes and seconds with 60 minutes making up a degree and 60 seconds comprising a minute.
