If you do much geographic work, you may wonder if you can use Excel to display longitude and latitude in a cell in terms of degrees, minutes, and seconds. There are three ways that a solution can be approached.
First, if you just want to affect the display, you can follow these steps:
Figure 1. The Number tab of the Format Cells dialog box.
Now, if you type a number such as 1234543 into the cell, it is displayed as 123 degrees, 45 minutes, and 43 seconds.
Sometimes, however, you may want to take a decimal value that represents latitude and longitude and display it in degrees, minutes, and seconds. For instance, you may want 122.44 (which is a decimal representation of degrees) to be displayed as 122 degrees, 26 minutes, and 24 seconds. This cannot be accomplished with formatting the cell in which the number is contained. Instead, you must use a formula to achieve the proper display. For instance, if 122.44 is in cell A7, then you can put the following in cell B7:
=TEXT(TRUNC(A7), "0" & CHAR(176) & " ") & TEXT(INT((ABS(A7) - INT(ABS(A7)))*60), "0' ") & TEXT(((((ABS(A7)-INT(ABS(A7)))*60) - INT((ABS(A7) - INT(ABS(A7)))*60))*60), " 0''")
This is a long formula, but it provides the desired formatting of the latitude or longitude value. The result is text, and cannot be used in any calculations. If you want to use a display instead, you can simply divide the decimal value of the latitude or longitude by 24, which converts it into the same value ranges used by Excel to represent times. Then you can format the display of the formula as follows:

I sail (on Georgian Bay) and frequently use Canadian Notices to Mariners to mark changes to the nautical charts in my GPS and chart plotter. The problem I had was the opposite of the one described by Allen. I needed to convert a position entry e.g., 44°54′56.6″N 080°09′52.3″W to decimal degrees entries for latitude and longitude. The position entry imported from NotMar is just a string of text giving both latitude and longitude. I needed two decimal numbers to upload into the two devices I use. To achieve this I created two user defined functions: LatDD(position) and LonDD(position). If you copy the code into your VBA editor, you can then align the numbering of the string characters so it is easy to see which parts of the string are extracted.
The functions depend on the position of each element, rather than using °, ', and " as delimiters. This could be done because NotMar is very consistent in formatting the position.
--------------------------------------------------
Public Function LatDD(PositionDMS As String) As Double
'Converts Position given in NotMar in DMS to Latitude in Decimal Degrees
'Requires PositionDMS to follow format like: 45°46'03.2"N 080°36'58.8"W
' in-string pos: 12345678901234567890123456
'this argument is a string of 26 characters and gives position with one decimal for seconds for both Lon and Lat
'will assume nothern latitude (+)
'A sister function is LonDD
Dim Degs As Double, Mins As Double, Secs As Double
Degs = Val(Left(PositionDMS, 2))
Mins = Val(Mid(PositionDMS, 4, 2))
Secs = Val(Mid(PositionDMS, 7, 4))
LatDD = Degs + Mins / 60 + Secs / 3600
End Function 'LatDD
Public Function LonDD(PositionDMS As String) As Double
'Converts Position given in NotMar in DMS to Latitude in Decimal Degrees
'Requires PositionDMS to follow format like: 45°46'03.2"N 080°36'58.8"W
' in-string pos: 12345678901234567890123456
'this argument is a string of 26 characters and gives position with one decimal for seconds for both Lon and Lat
'will assume western longitude (-)
'A sister function is LonDD
Dim Degs As Double, Mins As Double, Secs As Double
Degs = Val(Mid(PositionDMS, 14, 3))
Mins = Val(Mid(PositionDMS, 18, 2))
Secs = Val(Mid(PositionDMS, 21, 4))
LonDD = -(Degs + Mins / 60 + Secs / 3600)
End Function 'LonDD
