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.
The length of the equator is 3963.2 miles. The 1 degree latitudes are 3962.6 miles.
69 miles
About 69.2 miles (rounded)
The earth's circumference, at the equator, is approx 24,000 miles. 360 degrees = 24901.5 miles so 1 deg = 24901.5/360 = 1660 miles approx.
1.17MM
At 37 degrees north latitude, 1 degree of longitude is approximately 53 miles. The distance varies depending on the latitude due to the Earth's curvature.
Depends on the referenced point
One degree off course is sufficient enough to get a close look of the moon.
69 miles
Roughly 69 miles, it varies a little because of the earth's shape.
One degree of latitude is 69.06 miles. With this information, and knowing that there are 5,280 feet in a mile, this becomes a simple arithmetic problem.
Did you know that if you are off course by just one degree then for every mile that you travel you get 92 feet further away from the right heading.
About 69.2 miles (rounded)
The nautical mile is approximately one minute, that is, 1/60 degree.
One degree of latitude on Earth is equal to approximately 69 miles (111 kilometers).
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.
