If I know how many square feet I have and I know the thickness of the material I have how I convert these values to square feet?

Do you want to know the board feet or the square feet

if you wan to know board feet its thickness x width x length % 12 or 144 if your measuring in feet use 12 if its in inches then use 144 and that will give you the board feet.

If I have 2,699,956 square feet of product that has dimensions of 0.5" Thick by 48" wide and 96 inches long, how many board feet do I have? Please provide your calculations if possible. Thank you in advance for your help. Regards.

2,699.956 X .5= 1,349,978 board feet. The size of the individual boards doesn't matter.
