One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.
How many degrees are in a mile?
Each degree of latitude is approximately 69 miles (111 kilometers) apart. The range varies (due to the earth’s slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. This is convenient because each minute (1/60th of a degree) is approximately one [nautical] mile.
One minute of latitude is defined as one nautical mile (1 naut. mile or 1 nm, equivalent to 1.582 km), so one degree (1°) of latitude corresponds to 60 nautical miles or approximately 111 km. The length of one degree (1°) of longitude varies because the meridians converge towards the poles.

How many degrees are in a kilometer?
Near the equator, 1km is going to equal roughly 0.008 degrees (1 km / 40,000 km * 360 degrees) of latitude and longitude, but near the poles, 1km is going to equal roughly 0.008 degrees latitude, but could be many many degrees longitude.
How many meters are in a degree?
Converting NASA’s measurement of the Earth’s radius into meters and substituting it in the formula for arc length, we find that each degree the radius line of the Earth sweeps out corresponds to 111,139 meters. If the line sweeps out an angle of 360 degrees, it covers a distance of 40,010, 040 meters.
How many degrees is 2 inches?
What is a degree measure?
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. It is not an SI unit”the SI unit of angular measure is the radian”but it is mentioned in the SI brochure as an accepted unit.
How many feet are in a degree?
One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.
What is the difference of time in the difference of 1 degree longitude?
The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on.
What is the longest line of longitude?
Answer: The longest is the equator, whose latitude is zero, while at the poles, at latitudes 90° north and 90° south (or “90°), the circles shrink to a point. Both longitudes or meridians, interconnecting the north pole and the south pole, are equivalent lines of similar length.

Why are there minutes in coordinates?
If it was sensible, there would be 24 degrees not 360. It has nothing to do with time or the earth, angles of any circle are just measured 360 degrees, each degree split in to 60 mins, each min 60 secs. As mentioned above is just a unit, would be same for a football. 15 Degrees = 1 hour because 360 / 24 = 15.
