How many feet in one second of longitude?

Answer 1

The 'second' referred to is in reference to Degrees Minutes & Seconds Such As:

N 11°22'33" E (example) Where the 33" is the "Seconds".

However in the case listed above, the Degrees, minutes, and Seconds refers to a direction and not a location. The appropriate answer to the question refers to Latitude and Longitude, where you will express the degrees, minutes, and seconds as a location rather than a direction and will appear similar to this:

11°22'33" N, 11°22'33" W (example)

Answer in this scenario:

A degree covers about 69 miles. Divide that by minutes and find that there is about 1.15 miles in a minute. Divide that by 60 and you will find that there is about .019 miles in a second. Since there are 5280 feet in a mile, multiply .019 by 5280 to get about 101.20 feet in a second.

There are APPROXIMATLEY 101.20 FEET between two seconds of latitude or longitude.

Answer 2

About 101.1-ft at the equator, decreasing (as the cosine of the latitude) toward the poles. ,

Additional Information: At the equator . . .

One arc second = 1/60/60 degree = ~30 meter length = ~100 feet.,

One arc minute = 1/60 degree = ~1855 meters ~ one nautical mile ~ 6087 feet.

Answer 3

A second of longitude will correspond to different linear distances according to the latitude.

It corresponds to the longest distance, which is about 30.83 meters, on the equator. On the poles, a second of longitude corresponds to zero distance.

Answer 4

Knowing longitude and latitude are important for anyone who is reading a map or navigating a ship. There are 366,666 feet in one degree of longitude.

Answer 5

I get 72.22 feet.

I could be wrong.
