Curious if I am thinking about this right.

Half again (I probably should have tested this)

Code: (Select All)

Input "Enter a Number to convert "; num

Input "Enter 1 for conversion to mm from inches any other does vice versa "; op%

Print _IIf(op% = 1, num * 25.4, num / 25.4) ' 25.4 mm per inch

Are the Input questions not explanatory comment enough for the variables?

The beauty of Basic is that you don't have to Dim plain variables.

EDIT: a comment added to explain where the 25.4 number is coming from
