=VLOOKUP(cell*1000,lookup+table,3,False)

I have a column which I would like multiply by 1000 within the same column.
Basically this data is used in a vlookup in another sheet, so I cannot
move
the data or use a formula.
I was hoping to use a Custom Format.

Example
15 changed to 15000
45 changed to 45000
