How to Convert Degrees Minutes Seconds to Decimal Degrees in Excel

To denote angular dimensions, degrees, minutes, and seconds are commonly used (DMS). Because one minute equals 60 seconds and one degree equals 60 minutes, you may describe angular observations in degrees and decimal fractions of degrees to simplify mathematical calculations. This article explains some customized functions to convert degrees, minutes, and seconds to decimal degrees in Excel.

Convert Degrees Minutes Seconds to Decimal Degrees in Excel: 2 Ways

We’ll utilize Excel’s built-in options first, then use a formula to convert the degrees to decimal format in the sections below. Later on, we’ll use VBA code to create a custom option for decimal conversion. Here is an example data set that we will use to accomplish it.

1. Apply a Formula to Convert Degrees Minutes Seconds to Decimal Degrees in Excel

We’ll start by using a formula to convert degrees, minutes, and seconds to decimal format. To do so, we must first remove the degrees, minutes, and seconds symbols before using the formula. Follow the instructions below to do so.

Step 1:

• First of all, copy the degree (°)

Step 2:

• Select the cells.

Step 3:

• Click on the Data.
• Then, select the Text to Columns.

Step 4:

• Choose the Delimited.
• After that, click on the Next.

Step 5:

• From the options, click on the Other.

Step 6:

• Paste the degree (°).
• Then, click on the Next.

Step 7:

• After that, click on the Finish.

Step 8:

• Therefore, you see that degrees are separated and the symbols are removed.

Step 9:

• To remove the minutes (’) symbol, repeat the previous steps after copying the minutes (’).
• Simply, paste the minutes (’) symbol in the box.
• Then, click on the Next.

Step 10:

• As before, click on the Finish.

Step 11:

• Again, to eliminate the seconds (”) symbol, paste the symbol in the box.
• After that, select the Next.

Step 12:

• Finally, click on the Finish option again as we did before.

• As a result, the degrees will be separated into degrees, minutes, and seconds without the symbols.

Step 13:

• Type the formula in cell  F5  to convert the degrees, minutes, and seconds into decimal degrees.

Step 14:

• Press Enter to see the conversion.

Step 15:

• Use the AutoFill tool to autofill the next cells.

2. Run a VBA Code to Convert Degrees Minutes Seconds to Decimal Degrees in Excel

When converting degrees to decimal fractions, VBA offers a handy option. We’ll create a custom function to do the conversion in a matter of seconds, regardless of the symbols involved. Follow the steps outlined below to complete it.

Step 1:

• Firstly, press  Alt  + F11  to start a Macro.
• Click on the Insert.
• Then choose the Module.

Step 2:

• Paste the following VBA.

Function Convert_to_Decimal(Degree As String) As Double
    'At first Declare the variables
   Dim deg As Double
   Dim min As Double
   Dim sec As Double
   ' Replace Degree set degree to value before "°"
   Degree = Replace(Degree, "~", "°")
   deg = CDbl(Left(Degree, InStr(1, Degree, "°") - 1))
   ' between "°" and "'" set minutes to a value
   ' as for the Degree variable divided by
   ' 60. Val is a function that turns a text string into a number.
   min = CDbl(Mid(Degree, InStr(1, Degree, "°") + 1, _
             InStr(1, Degree, "'") - InStr(1, Degree, "°") - 1)) / 60
   ' Set the second counter to the number to the right of "'," which is
   ' changed to a number, and after that divided by 3600
   sec = CDbl(Mid(Degree, InStr(1, Degree, "'") + _
           1, Len(Degree) - InStr(1, Degree, "'") - 1)) / 3600
   Convert_to_Decimal = deg + min + sec
End Function

• Save the program and press  F5  to run it.

Step 3:

• Therefore, you will see a new function will appear named Convert_to_Decimal. Simply, write the following formula.

• As a result, you will get the changed value of the degree.

Step 4:

• Finally, use the AutoFill tool to fill the next cells.
