Here. Try this. The way you had it set up, any cell with a value of
for example, exactly two, wouldn't be changed. If you have an
questions about what I did, please let me know. ALSO, I have no
tested this, but it works in theory... - Pikus

Dim grv As Long
Dim lrow As Long
Application.ScreenUpdating = False

With Worksheets("Horizon_Measurements")
lrow = .UsedRange.Row - 1 + .UsedRange.Rows.Count
For grv = 1 To lrow
If (Cells(grv, 19).Value) = 0 Then
.Cells(grv, 19).Value = "N"
ElseIf .Cells(grv, 19).Value 0 And .Cells(grv, 19).Value <= 2 Then
.Cells(grv, 19).Value = "C"
ElseIf .Cells(grv, 19).Value 2 And .Cells(grv, 19).Value <= 5 Then
.Cells(grv, 19).Value = "F"
ElseIf .Cells(grv, 19).Value 5 And .Cells(grv, 19).Value <= 15 Then
.Cells(grv, 19).Value = "C"
ElseIf .Cells(grv, 19).Value 15 And .Cells(grv, 19).Value <= 40 Then
.Cells(grv, 19).Value = "M"
ElseIf .Cells(grv, 19).Value 40 And .Cells(grv, 19).Value <= 90 Then
.Cells(grv, 19).Value = "A"
ElseIf .Cells(grv, 19).Value 90 Then
.Cells(grv, 19).Value = "D"
End If
Next grv
End With
