It is the average length of one minute of one degree along a great circle of the Earth. One nautical mile corresponds to one minute of latitude. Thus, degrees of latitude are approximately 60 nautical miles apart.
Answer: 4 minutes take time does one longitude take to pass by the sun.
As such, it is easy to convert latitude into miles. Divide the amount of miles by the degrees in a circle. The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles.
The Equator is at 0°, and the North Pole and South Pole are at 90° north and 90° south, respectively. The Equator is the longest circle of latitude and is the only circle of latitude which also is a great circle.
The distance between longitudes at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.
Are lines of longitude and latitude all the same length? No, they are not. Only the lines of longitude are of equal length. Each line of longitude equals half of the circumference of the Earth because each extends from the North Pole to the South Pole.
Since the cosine of 40° is 0.766, x = (4,000)(0.766) = 3,064 miles. You now have the radius of a circle going around the Earth at 40° north (or south) latitude, and using the formula for circumference (2πr). you find that this circle is 19,252 miles around.
Latitudes are imaginary lines that run from west to east, ranging from zero to 90 degrees. … The North and South Poles are at 90 degrees from the equator. The distance from the equator to the poles is 1/4th of the circle around the earth.
For the conversion you ask for, decimal degrees = feet / 364,567.2. Derivation: a nautical mile (nm) is 1 minute of arc along a great circle*, or 1/60th of a degree. There are 6076.12 feet per nautical mile. So, 6076.12 x 60 = 364,567.2 feet per degree.
The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart. At the equator, a grid of 1° of longitude by 1° of latitude covers about 3,600 square miles.
To achieve a 30 degree angle you would need to raise the head of the bed about 41 inches… or you can sleep on one of our adult wedges that only raise your upper body to a 30 degree angle. We also have wedges with small and greater degrees.
When we describe the Earth in spherical coordinates it is called Geographic, or Un-projected. The lines running North to South are called lines of longitude, while the lines running East to West are called lines of latitude. In other words, the Earth is 360 degrees around. …

The knot (/nɒt/) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s).
