You can do this with an Event macro:
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Range("A1")) Is Nothing Then Exit Sub
Application.EnableEvents = False
Target.Value = 60 * Target.Value
Application.EnableEvents = True
End Sub
It is coded to operate on cell A1.
Because this is worksheet code, it is very easy to install and automatic to
use:
1. right-click the tab name near the bottom of the window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window
If you have any concerns, first try it on a trial worksheet.
If you save the workbook, the macro will be saved with it.
To remove the macro:
1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window
