# Are there 360 or 361 Longitudes?

Is it 360 or 361 Degrees Longitude? How many Longitude Degrees are there? Why are there 360 Longitude Meridians? How many Total Latitudes exist?

Longitude is an imaginary north-south line that runs through both geographic poles and Greenwich, London. Longitude is the number of arcs drawn from Earth’s center to where the Prime Meridian and the Equator meet, and then another line from Earth’s center to any point on the Equator. Are there 360 or 361 longitudes? Well, a degree of longitude is 69.172 miles or 111.321 kilometers wide at the Equator. They say that the latitude is 180 and 360 longitude is the total number of degrees. You’re wondering why there are 180 latitudes but only 360 longitudes and not 361? In this blog, we will answer all such queries.

### 1. How many Degrees of Longitude are there?

Longitude is calculated by artificial boundaries that go vertically around the Earth and meet at the North and South Poles. Additionally, it is measured in minutes, seconds, and degrees. These imaginary lines are called meridians. Each meridian corresponds to 1 arc degree longitude. The Earth’s circumference is 360 degrees. Longitude lines travel north-south and denote the position of a point east-west. (See What is the Imaginary Line that Runs from the Geographic North To South Pole?)

### 2. How many Longitudes are there and What are they?

There are 180 vertical lines east and 180 vertical lines west of the Prime Meridian for measuring longitude. These longitude locations are expressed as degrees east or degrees west. The International Date Line is a single vertical line that runs immediately opposite the Prime Meridian at 180 degrees. It separates the planet into the Eastern and Western Hemispheres. So, there are 360 longitudes or degrees of longitude in total. (See What is Imaginary Line?)

### 3. Why there are 360 Meridians of Longitude?

Longitudes and latitudes are imaginary circular lines traveling from north to south and west to east, respectively. Because circles are measured in degrees in mathematics, latitudes and longitudes are likewise measured in degrees. Because a circle has 360 degrees, there are 360 meridians of longitude.

### 4. Why are there 360 Longitudes and Not 361?

We should have 361 longitudes total, but we only have 360. There is an explanation for this: there are 360 longitudes +1 of the Equator which equals 361. However, when we build a curve of 180 eastern longitudes + 180 western longitudes, we find that the 180th-degree longitude is common on both sides since they overlap while making a circle.

### 5. Are there 360 Lines of Longitude?

Yes, there are 360 lines of longitude

### 6. Are there 360 or 361 Longitudes?

This is known as the 180th meridian and the international date line. As a result, the total latitudes and longitudes are 180 and 360, respectively. This would have answered your question: are there 360 or 361 longitudes?

### 7. Are there 361 Meridians?

No, the westernmost longitude is 180W, while the easternmost longitude is 180E; 180W and 180E are coincidentally the same. As a result, there are 360 longitudes in total.  (See Where does Earth End and Outer Space Begin?)

### 8. Are there 181 Longitudes?

No, Because the Earth’s longitude is 360 degrees, the 180-longitude line is the halfway point from the prime meridian.

### 9. How many Total Latitudes are there?

While asking, are there 360 or 361 longitudes, you might ask how many total latitudes are there. There are 180 latitudes on the planet. Every point on the planet would be visited twice! As a result, the latitude needs to span 180 degrees from the north to the south. (Also read What are the Effects of Latitude on Climate?)

### 10. Why Latitude is 180 and 360 Longitude?

Longitude lines are essentially half-circles. Thus, there are 360 of them if you space them out at a 1° arc. Latitude lines are perfect circles, with the Equator at 0 degrees and the pole at 90 degrees. The North and South Poles are 180° apart from each other. Hence, there are 180 latitude lines, with the North Pole and the South Pole forming a circle with zero diameters. (See What is the Difference between Tropical and Polar Regions?)

### 11. What is Maximum Longitude and Latitude?

Latitude and longitude are two numbers (coordinates) that describe a point on a geographic coordinate system’s plane. The figures are in decimal degrees and range from −90 to 90 degrees latitude and −180 to 180 degrees longitude. (See What is the Difference between Latitude and Longitude?)
