Converting from Decimals to Feet and Inches

[beezy]

I followed the directions below and but it is not working. Please Help.








Use the Excel Custom Functions of Feet() and LenText to Convert Lengths in Feet and Inches to Decimal Feet and Back

I have an Excel spreadsheet with a column of lengths in the format of 12' 6 7/8". How can I use Excel to convert this to decimal feet? I don't want to split the column into two parts. Then, how can I convert back to feet and inches in Excel?.

The custom function feet() shown below will take a text field in the format that you describe and convert it to decimal feet.
The custom function LenText will convert a decimal number of feet into a text field showing feet, inches, and fractional inches to the nearest 1/32".
To enter the custom function,

• Start the VB editor with alt-F11.
• Insert>Module.
• Insert>Procedure.
• Type feet as the name of the procedure and indicate it is a function.
• Then, copy the following code:

Public Function feet(LenString As String)
Dim FootSign As Integer
Dim InchSign As Integer
Dim SpaceSign As Integer
Dim FracSign As Integer
Dim InchString As String
Dim Word2 As String
' Copyright 1999, 2005 MrExcel.com
LenString = Application.WorksheetFunction.Trim(LenString)
'The find function returns an error when the target is not found
'Resume Next will prevent VBA from halting execution.
On Error Resume Next
FootSign = Application.WorksheetFunction.Find("'", LenString)
If IsEmpty(FootSign) Or FootSign = 0 Then
' There are no feet in this expression
feet = 0
FootSign = 0
Else
feet = Val(Left(LenString, FootSign - 1))
End If

' Handle the case where the foot sign is the last character
If Len(LenString) = FootSign Then Exit Function
' Isolate the inch portion of the string
InchString = Application.WorksheetFunction.Trim(Mid(LenString, FootSign + 1))
' Strip off the inch sign, if there is one
InchSign = Application.WorksheetFunction.Find("""", InchString)
If Not IsEmpty(InchSign) Or InchSign = 0 Then
InchString = Application.WorksheetFunction.Trim(Left(InchString, InchSign - 1))
End If

' Do we have two words left, or one?
SpaceSign = Application.WorksheetFunction.Find(" ", InchString)
If IsEmpty(SpaceSign) Or SpaceSign = 0 Then
' There is only one word here. Is it inches or a fraction?
FracSign = Application.WorksheetFunction.Find("/", InchString)
If IsEmpty(FracSign) Or FracSign = 0 Then
'This word is inches
feet = feet + Val(InchString) / 12
Else
' This word is fractional inches
feet = feet + (Val(Left(InchString, FracSign - 1)) / Val(Mid(InchString, FracSign + 1))) / 12
End If
Else
' There are two words here. First word is inches
feet = feet + Val(Left(InchString, SpaceSign - 1)) / 12
' Second word is fractional inches
Word2 = Mid(InchString, SpaceSign + 1)
FracSign = Application.WorksheetFunction.Find("/", Word2)
If IsEmpty(FracSign) Or FracSign = 0 Then
' Return an error
feet = "VALUE!"
Else
If FracSign = 0 Then
feet = "VALUE!"
Else
feet = feet + (Val(Left(Word2, FracSign - 1)) / Val(Mid(Word2, FracSign + 1))) / 12
End If
End If
End If
End Function
</pre> Repeat for the function called LenText. Use this code:

Public Function LenText(FeetIn As Double)
' This function will change a decimal number of feet to the text string
' representation of feet, inches, and fractional inches.
' It will round the fractional inches to the nearest 1/x where x is the denominator.
' Copyright 1999 MrExcel.com
Denominator = 32 ' must be 2, 4, 8, 16, 32, 64, 128, etc.
NbrFeet = Fix(FeetIn)
InchIn = (FeetIn - NbrFeet) * 12
NbrInches = Fix(InchIn)
FracIn = (InchIn - NbrInches) * Denominator
Numerator = Application.WorksheetFunction.Round(FracIn, 0)
If Numerator = 0 Then
FracText = ""
ElseIf InchIn >= (11 + (31.4999999 / 32)) Then
NbrFeet = NbrFeet + 1
NbrInches = 0
FracText = ""
ElseIf Numerator = Denominator Then
NbrInches = NbrInches + 1
FracText = ""
Else
Do
' If the numerator is even, divide both numerator and divisor by 2
If Numerator = Application.WorksheetFunction.Even(Numerator) Then
Numerator = Numerator / 2
Denominator = Denominator / 2
Else
FracText = " " & Numerator & "/" & Denominator
Exit Do
End If
Loop
End If
LenText = NbrFeet & "' " & NbrInches & FracText & """"
End Function
</pre>

Both functions work correctly for me. Given your example of 12' 6 7/8" in A1, B1 containing =feet(A1) displays 12.57291667, and C1 containing =lentext(B1) displays 12' 6 7/8". Oddly named functions IMO, but they work as expected.

Describe exactly what is not working for you.
