The distance along one degree of longitude is 60 nautical miles at the equator and less at latitudes away from the equator. In fact it is 60 nautical miles times the cosine of the latitude, so 60 at the equator zero at the poles, and 30 nautical miles at 60 degrees north or south..
The number of kilometers in each full rotation of Earth depends on your latitude. Actually, it's the entire length of your latitude, which is roughly 40,075 km times the cosine of your latitude.
In latitude, 1 second is equivalent to roughly 30.8 meters. In latitude, 1 second is equivalent to roughly 30.8 meters along the equator, and it shrinks steadily to zero at the poles. In general, it's 30.8 meters multiplied by the cosine of the latitude where it's being measured.
-- Since every point on a line of latitude has the same latitude, the line has no thickness. -- Its length depends on its latitude. -- The line at zero latitude, known as the 'equator', is a great circle and so its length is the circumference of the Earth ... about 24,900 miles. -- Every other line of latitude is a small circle. Its length is 24,900 miles times the cosine of the latitude which it marks. -- The distance between any latitude and the one that's 1° north or south of it is about 111.1 kilometers (69 miles).
A point on the Earth's surface moves at approximately(1,670 kilometers per hour) x (cosine of its latitude).-- 1,670 kilometers per hour on the equator.-- 1,446 kilometers per hour at 30° latitude-- 1,181 kilometers per hour at 45° latitude-- 835 kilometers per hour at 60° latitude-- 432 kilometers per hour at 75° latitude-- zero at the poles
1 degree of latitude represents the same distance everywhere . . . about 111 km. 1 degree of longitude represents a distance of (111 km) x (cosine of the latitude). That's about 111 km along the equator and dwindles to zero at the poles, because all of the longitudes converge (meet, come together) at the poles.
Cosine = Adjacent/hypotenuse
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
The number of kilometers in each full rotation of Earth depends on your latitude. Actually, it's the entire length of your latitude, which is roughly 40,075 km times the cosine of your latitude.
It is cosine*cosine*cosine.
The Prime Meridian is defined as zero degrees of longitude. The distance in miles between degrees of longitude depends on the latitude; one degree of longitude equals the cosine of the latitude * 60 nautical miles. Note: If you're using Excel or some other spreadsheet program, be sure to convert degrees into radians before calculating the cosine of the latitude.

60 at the equator, decreasing steadily to zero at the poles. In general: (60) times (the cosine of the latitude).
That would be the equatorial circumference times the cosine of 38 degrees. I get 19,605 miles (31,552 km) .
Cosine 0 is 1
In latitude, 1 second is equivalent to roughly 30.8 meters. In latitude, 1 second is equivalent to roughly 30.8 meters along the equator, and it shrinks steadily to zero at the poles. In general, it's 30.8 meters multiplied by the cosine of the latitude where it's being measured.
