1. You would need to use worksheet change events and parse it
Private Sub Worksheet_Change(ByVal Target As Range)
Dim part1 As String, part2 As String
On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("AA1:AA100")) Is Nothing Then
part1 = Left(.Value, InStr(1, .Value, ".") - 1)
part2 = Right(.Value, Len(.Value) - InStr(1, .Value, "."))
.Value = (Val(part1) * 60 + Val(part2)) / 1200
Application.EnableEvents = True
'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.
