This article provides a sample Microsoft Excel macro type (XLM) to convert a degree value stored in decimal format (base 10) to degrees, minutes, and seconds as text. Microsoft Excel does not provide a number format to do this.


Fractions of a degree are commonly expressed in units called minutes and seconds. One degree is equivalent to 60 minutes, and similarly one minute equals 60 seconds. These units are most commonly used with nautical charts and navigation.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following function macro will accept an angle formatted as a decimal number and convert it to degrees, minutes, and seconds as text.
   A1:     Convert_Degree
   A2:     =ARGUMENT("Decimal_Deg")
   A3:     =RESULT(2)
   A4:     Degrees=INT(Decimal_Deg)
   A5:     Minutes=(Decimal_Deg-Degrees)*60
   A6:     Seconds=ROUND((Minutes-INT(Minutes))*60,0)
   A7:     =RETURN(Degrees&"~ "&INT(Minutes)&"' "&Seconds&"""")
For example, entering =Convert_Degree(10.46) into a worksheet returns 10~ 27' 36" (10 degrees, 27 minutes, 36 seconds).
