(Nota: “It is common to arrive at this conclusion… but 33 degrees, 33 minutes in latitude or longitude are measured this way: 33 degrees (33 x 60 = 1,980 miles, + 33 minutes = 2013) Because the calculation is in minutes and seconds, the actual number is 2,102.9 ( at 60 seconds the minutes jumps to 34.)” http://derekpgilbert.com/?p=2405)
