# Difference Between Longitude and Latitude

## Core difference

The main difference between Longitude and Latitude is that Longitude specifies the east-west location of any point on the earth’s surface, while Latitude specifies the north-south location of any point on the earth’s surface.

## longitude vs. latitude

Longitude is a geographic coordinate that represents the distance of any point from the east or west of the prime meridian. On the other hand, latitude is the geographic coordinate that represents the distance of any object or area from the north or south of the equator.

Longitude is indicated by a Greek letter lambda (λ), but latitude is indicated by a Greek letter phi (Φ). Longitude is from north to south and ranges from 0 to 180 degrees, while latitude is from east to west and ranges from 0 to 90 degrees.

Longitude is in the form of vertical lines on the map. On the other hand, latitude is in the form of horizontal lines. So longitudes are also known as meridians while latitudes are also called parallels. Also, the reference lines in longitude are not parallel to each other, while the one in latitude is parallel to each other.

Total longitude lines are 360. On the other hand, total latitude lines are 180 in number. Longitudes used to classify time zones. On the other hand, latitudes are used to classify heat zones, for example, temperate zone, torrid zone, and frigid zone.

 Length Latitude A geographic coordinate that represents the distance of any point from the east or west of the prime meridian is known as longitude. The geographic coordinate that represents the distance of any point from the equator north or south is known as latitude. Source The word “Longitude” originated in Late Middle English, from the Latin word “longitudo” and from “longus” meaning “long”. The word “latitude” is derived from Late Middle English, from the Latin word “latitude” meaning “width” and from “latus” meaning “wide.” Also know as Longitudes are also known as meridians. Latitudes are also called parallels. Direction It has a north-south direction. Latitude runs from east to west. Rank It varies from 0 to 180° East and West. The latitude range is between 0 and 90° North and South. denoted by Length denoted by a Greek letter lambda (λ). Latitude denoted by phi (Φ), which is a Greek letter. Distance from The longitude denotes the distance from the prime meridian, that is, east or west. Latitude denotes the distance from the equator, that is, north or south. Lines It does not have reference lines parallel to each other. Latitude has parallel reference lines. Number of lines The total length lines are 360 ​​in number. The lines of total latitude are 180 in number. length of the lines Lines of longitude have the same length. Latitude lines show unequal longitude. Hemisphere Locations at a common longitude may fall into different hemispheres. All locations that are present at a common latitude exist within the same hemisphere of the earth. Time zone All locations that are present in the same longitude exist in the same time zone. All locations that are present within the same latitude are not necessarily present in the same time zone. notable lines Its notable line is the Greenwich meridian. Its important lines are the Tropic of Cancer, the Equator and the Tropic of Capricorn. Classify Longitudes are used to order time zones. Latitudes are used to classify heat zones, for example, temperate zone, torrid zone, and frigid zone. Measurement It is measured in seconds, minutes and degrees. It is also measured in seconds, minutes and degrees.

## What is length ?

Longitude is a geographic coordinate that represents the distance of any point from the east or west of the prime meridian. It is derived from Late Middle English, from the Latin word “longitudo” and from “longus” meaning “long”. The length is used to find out the distance from a particular point to the reference line. Also called meridians.

Length is denoted by lambda (λ), which is a Greek letter. Its direction is from north to south and varies from 0 to 180° East and West. The vertical lines of longitude are the same length, and the total number of lines of longitude is 360. It is measured in seconds, minutes, and degrees.

It is the angular distance of a point, west of the standard meridian or east or west of the prime meridian. The meridians of longitude are the reference lines that run from the north pole to the south pole. These are in the shape of semicircles that all meet at the poles. So their distance keeps steadily decreasing toward the poles.

All meridians have a similar length. Therefore, the Greenwich meridian is used as the prime meridian and its value is 0° longitude. The longitude of various areas can be determined as the east or west angle of the prime meridian. On the prime meridian, it varies between 0° and +180° to the east and -180° to the west. The prime meridian separates the earth into two equal parts which are the western hemisphere and the eastern hemisphere. Locations at a common longitude may fall into different hemispheres.

Longitudes are used to classify time zones. All locations that are present in the same longitude exist in the same time zone. The Prime Meridian at 0° and the International Date Line at 180° are the most important longitudes. They are placed on the reverse side of the Earth.

The international date line denotes the place where each day officially begins. Therefore, the west side of the International Date Line is always one day ahead, and then the east side. So that’s the reason the Earth rotates from west to east. The prime meridian symbolizes the position of Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC). All other time zones are indicated with offsets, ie positive or negative from GMT/UTC.

In our daily life, the longitude of any place can be found by using the time difference between UTC and that place. The sun travels at a speed of 15 degrees per hour (360°/day) across the sky. Therefore, if the time zone or standard time is three hours faster than UTC, then that place is located around 45° longitude, i.e. 3 hours × 15° per hour = 45°. Also, the longitudes converge at the poles, so the measurement can become inaccurate at the poles.

## What is Latitude ?

Latitude is a geographic coordinate that characterizes the distance of any point from the north or south of the equator. This word is derived from Late Middle English, from the Latin word “latitude” meaning “width” and from “latus” meaning “wide.” It also worked as a reference point to find different places on earth. It is also recognized as parallel.

Latitude is denoted by phi (Φ), which is a Greek letter. Its direction is from east to west and varies from 0 to 90° north and south. The lines of latitude are of unequal length, and the total number of lines of latitude is 180. It is also measured in seconds, minutes, and degrees.

Latitude denotes the distance from the equator, which is an imaginary circular line and divides the Earth into two equal parts. Here, the upper half is known as the northern hemisphere, while the lower half is called the southern hemisphere. Circular lines that are parallel to the equator and extend to the north and south poles are known as parallels of latitude.

The latitude range is between 0 degrees and 90 degrees. Here the equator specifies 0° latitude and the poles are at 90°. Parallels that meet in the northern hemisphere are taken as northern latitudes. On the other hand, those present in the southern hemisphere are known as southern latitudes. All locations at a common latitude exist within the same hemisphere of the earth, but all locations that are present within the same latitude are not necessarily present in the same time zone.

Latitudes are used to classify heat zones, for example, temperate zone, torrid zone, and frigid zone. Some important parallels of latitude are the Tropic of Cancer (23.5°N), the Arctic Circle (66.5°N), the Tropic of Capricorn (23.5°S), and the Antarctic Circle (66.5°N). S).

## conclusion

The discussion above summarizes that longitude and latitude combine to form a coordinate system that is used to find the location of any place. Longitude is the geographic coordinate that represents the distance of any point from the east or west of the prime meridian. On the other hand, latitude means the distance of any place or object from the north or south of the equator.
