Curious if I am thinking about this right.

Well so Steve can get a good nights sleep tonight:

Code: (Select All)

Print Val(_InputBox$("Convert number from inches to mm.", "Enter a number")) * 25.4, Val(_InputBox$("Convert number from mm to inches.", "Enter a number")) / 25.4

It's up to the user if he wants to enter the same number both times, so hey it's a little more flexible.

Beat you to it. Try my insane code above yours.
