Degrees of longitude are uniform in length. 1 degree (Longitude) = 69.69 miles*Cos(Ө)(latitude) however the length of a degree of latitude depends on were you are on the planet. A degree of latitude at the equator is notable longer than, for example, a degree of latitude at the latitude of Toronto, Canada.
Latitude and longitude are measured in degrees, not metres. Because the earth is (roughly) spherical, 1 degree along the equator is much larger than 1 degree nearer the poles. The formula for converting degrees to metres would need adjusting for distance from the equator. Although mathematically, this is not difficult to define, it is not particularly advantageous for most purposes. The metre was originally defined as one ten millionth of the distance from the equator to the North Pole along the longitude passing through Paris. That definition is no longer used, but is still sufficiently accurate.
That depends on where you are on Earth, specifically, your latitude. All meridians of longitude converge (meet, come together) at the north and south poles, so any two of them get closer and closer together as you get closer to either pole. One degree of longitude is about 69 miles along the equator, but only 48.8 miles at latitude 45°, 17.9 miles at latitude 75°, and about 6 miles at latitude 85°. So as you get farther from the equator, your 1° x 1° square is getting progressively skinnier. Here's the area of your square at a few different latitudes. Each square is 1 latitude degree tall and 1 longitude degree wide, and the indicated latitude goes straight across its middle: On the equator . . . . . 4,760 square miles 30° . . . . . 4,150 square miles 45° . . . . . 3,375 square miles 60° . . . . . 2,400 square miles 85° . . . . . 415 square miles

One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). One degree of latitude, and of longitude on the equator only, is also equal to about 60 nautical miles.
One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). One degree of latitude, and of longitude on the equator only, is also equal to about 60 nautical miles.
we can measured the longitude by north pole and south pole by equator
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.
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.
The equator is mapped out to be positioned as the 0º line of latitude.
0 longitude is the prime meridian. 0 latitude is the equator.
The distance represented by one degree of longitude varies according to distance from the equator. That's because the meridians of longitude are equally distributed around the equator but all converge to a single point at the north and south poles. The greatest distance between any two meridians of longitude, then, is the distance between the points where they cross the equator. Along the equator, one degree of longitude covers about 111.1 kilometers.
The equator is composed of all the points that have zero latitude and every possible longitude.
At the equator, one degree of longitude corresponds to about 69 miles.
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.
