I'm trying to figure out a way (if there's one) to enter a number into a
blank cell and have it automatically multiply that cell by 25.4
(essentially
converting a number from in. to mm.), keeping the new number in that same
cell: enter 2 into A2 and it converts it to 50.8 and A2 now shows 50.8.

Is this possible?

Thanks.
