One degree of longitude is approximately 69 miles (111 km) length at the equator.The distance between lines of longitude, however, gets smaller as you move towards the poles (North or South) since all the lines converge there.

How much time does each longitude line measure?

There is no standard set of "lines", so if you want to compare two "lines", you have to specify which two you're talking about. The Earth turns through 360 degrees of longitude in 24 hours. So every 15 degrees of longitude corresponds to one hour of rotation. If you want the clock to read 12:00 Noon when the sun peaks in the sky everywhere, then you have to change the clocks by one hour for every 15 degrees of longitude.

Well hello. How are you?

At the equator, both longitude and latitude measure approximately 60 nautical miles. This converts to 69.046767 statute miles. Both latitude and longitude degree lengths change with respect to latitude; latitude however changes very minimally between the equator and the poles, the distance only changes by about 75 meters between 0 degrees (the equator) where the degree length is 110574 meters, and 90 degrees (the north pole) the degree length of latitude is 111694 meters (note: miles = meters/1609.344) Longitude however changes quite a lot from the equator to the poles, at 90 degrees the degree length of longitude is 0, where as at the equator it is 111320m. There are a number of ways of finding the degree length, for close enough approximations it is usually said that the degree length of latitude does not change, lets say it's=111132m (it's that around 45 degrees of latitude), and degree length of longitude is then computed as: L - latitude in radians Longitude = 111132*cos(L) (note: here that since its a trig function you have to convert degrees to radians, which can be done with radians = degrees*pi/180) A much more close approximations for arcdegree lengths, based on an ellipsoid earth are: (Radii based on WGS-84 ellipsoid, used by all current GPS devices) E - equatorial radius - 6378137 P - polar radius - 6356752.314 L = latitude in radians Latitude = (pi/180)*((PE)2/((E*cos(L))2+(P*sin(L))2)3/2) Longitude = (pi/180)*cos(L)*(P2/((E*cos(L))2+(P*sin(L))2)1/2)
