# World Map Explained #2 | Latitude, Longitude, Minutes, Seconds, Nautical Miles

## Latitude

Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around Earth east-west, parallel to the Equator.

• All lines are parallel and not equal in length
• There are 90 lines above equator and 90 below equator and one equator self so total lines are 181
• The gap between each line is 1 degree
• 1 degree in latitude is equal to 111KM.

## Longitude

Longitude is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth.

All lines are almost equal if we thing earth is circular

There are total 360 lines.

The gap between each line is 1 degree

1 degree In longitude is equal to 111.3KM.

## Minutes, Seconds, Nautical Miles

The degree is divided into its sub unit minute. There are 60 minutes between two degrees.

Every minute is divided into 60” seconds

Distance on water is measured in nautical miles , and one nautical mile is equal to one minute of latitude.
