The circumference of the earth at the equator is 360 degrees. Each degree of lattitude is 60 minutes. 60 minutes equals 1 nautical mile, 360 X 60 equals 21600 nautical miles.
A nautical mile is 1,852 meters, or 1.852 kilometers, which is longer than a statue or imperical miles The shortest mile is the metric mile at 1500m.
360 degrees x 60 minutes = 21,600 minutes of arc for full circumference = 21,600 nautical miles (one minute of arc at equator = one nautical mile). 21,600 nautical miles = 24,872.7272...statute miles = 40,028.7 kilometres. For all practical purposes 40, 000 km. = circumf. at equator.
The circumference of Earth is approximately 24,901 miles, and the diameter is about 7,917.5 miles.
google it :P (The circumference of the earth at the equator is 24,901.55 miles)
The Earths circumference at its widest point, the equator, is about 24,500 miles (off the top of my head)
A degree of Latitude is 69 miles or 110kms
At the equator the circumference of the earth is roughly 40 000 km. To change this to nautical miles find out how many feet that is (times it by 3280 as thats how many feet there are in a km and then divide that answer by 6080 (feet in a nautical mile) to give you circumference of the earth at the equator = 21,578 nautical miles. Because the circumference at 60N will be much smaller we use 21, 578*cos lat (60 in this case). This gives us 10, 789 nautical miles.
The equatorial circumference of the Earth is approximately 24,901 miles.
The diameter of Earth at its equator is 12,756 km and its circumference is about 40,075 km.
The circumference of the Earth at the equator is 24,902 miles. From pole to pole is 24,860 miles.
360 degrees is the circumference, 25,000 miles round the equator, so divide 25,000 by 360 and then divide by 4 to find the number of miles in ¼ degree.
The circumference of the Earth one foot above the equator would be approximately the same as the circumference at the equator itself, which is about 24,901 miles.
Earth's Circumference is 24,901 miles (40,075 km)
