The diameter of Earth, measured around the equator, is 12,756 km (7,926 mi). since there are 3600 minutes in a circle (60 x 60 degrees = 3600 minutes), each minute represents a distance of 3.543 km (about 2.2 mi).
... or a nautical mile!
That's like asking "How many different marks are there in one foot ?"
You can split up one minute of longitude into as many tiny pieces as you
want to, and draw a line at the edges of each tiny piece. There is no official,
standard set of lines.
The distance of 1 degree longitude at the equator is approximately 111 kilometers, which is based on the Earth's circumference at the equator being about 40,075 kilometers.
That was the original definition of the nautical mile, but it's not exact.
1.15 statute miles (1.85 km) is pretty close.

What is the distance between two longitudes at the equator?
At the equator, the circumference of the Earth is 40,075.16 km ( 24,901.55 miles). Divide that into 360 equal pieces to get the distance for each one degree of longitude. A degree of longitude at the equator is equal to 111.32 km.
What distance is spanned by 1 grade of longitude at the equator?
One grade of longitude spans a distance of approximately 111 kilometers at the equator.
Why is the distance on a map showing 1 degree of longitude smaller than 1 degree of latitude yet both represent the same angle?
This difference is due to the Earth being a sphere, causing lines of longitude to converge towards the poles. At the equator, 1 degree of latitude is about the same distance as 1 degree of longitude, but as you move towards the poles, the lines of longitude get closer together. This distortion in map projection causes the discrepancy in distance measurements between lines of latitude and lines of longitude.
How wide is 1 deg longitude?
The width of 1 degree of longitude varies depending on the latitude. At the equator, 1 degree of longitude is approximately 111 kilometers. However, this distance decreases as you move towards the poles due to the convergence of the lines of longitude.
What does 1 degrees of latitude equal?
Only at the equator. The linear distance covered by 1 degree of longitude gets progressively smaller as you progress towards the poles, but 1 degree of latitude remains constant.

How does the linear distance separating each 1 degree of longitude change as you move from the equator toward the poles?
The linear distance across each degree of longitude at the equator is about 60 miles. That's as far apart as those lines of longitude get. As the lines of longitude run north (or south) to the north (south) pole, they converge until they all meet at the pole. That translates like this: the linear distance separating each degree of longitude is a maximum at the equator, and decreases to zero at the pole.

What is A difference of 1 degree in longitude at the equator is equivalent to nearly?
111km
Why is there a difference in nautical miles 1 degree longitude between the equator and the poles?
Because all 360 degrees of longitude are evenly distributed around the whole Earth,but that whole distance around shrinks as you move from the equator to the poles.Along the equator, one degree of longitude is about 69 miles (111 km). That distanceprogressively shrinks as you move away from the equator, and exactly at the poles,it's zero! All longitudes converge (come together) at the poles.
How many miles does one degree of longitude cover?
That's going to depend on how far you are north or south of the equator. The distance between any two meridians of longitude is maximum along the equator, and it shrinks to zero at the poles, where all meridians of longitude converge (come together). One degree of longitude represents about 111.2 km (69.1 miles) on the equator. Anywhere else on earth, it would be 111.2 multiplied by the cosine of your latitude.
What happens to a degree of longitude as you move from equator towards the poles?
As you move from the equator towards the poles, a degree of longitude appears to become shorter. This is because the lines of longitude converge towards the poles, so the distance covered by one degree decreases.
Why does the distance between 1 degree longitude decrease from the equator towards the poles?
The distance between 1 degree of longitude decreases towards the poles due to the convergence of the lines of longitude at the poles, which are closer together compared to at the equator. This happens because the Earth is a sphere and not flat, and the lines of longitude converge towards the poles.
What is 1 degree of longitude?
One degree of longitude is approximately 69 miles (111 km) apart at the equator; since they converge at the North and South Poles, the distance gets smaller as they near the poles.
