What is longitude

The hypothetical lines that divide the equator into 360 equal parts, which are assumed to cut the equator upright in the world and cross the polar points, are called longitude. Also known as the Merdeen.

Between two meridians, the largest range on the equator and is 111 km. In the city of Greenwich, the initial meridian, the meridian assumed to pass through Greenwich Observatory.

Each meridian is 4 minutes compared to the return speed of the world and has a total of 360 meridians. So, 4x360 = 1440 min = 24 hours. World time zones are also calculated through meridians. Apart from this, paralel (latitude) and meridians (longitude) are used in the calculation of the coordinates of a point in the world.

For example, the geographical coordinates of our country are among the 36O-42o north parallels and 26o-45o eastern meridians.
