Entering imperial units

Morning all,
i want a user to enter a Length in s Data-Shape dialog. Any idea how to go about it?

Can i transforn a 1’ 6" into something Dynamo will use?



Make sure to program a means to rerun the input if they don’t type it 1’-6" and instead type 1’6 or 1’6" or… we’ll you get the idea.
