Glass Thickness for 180 gal

[Grassman]

Does anyone know how thick the glass on all for sides & the bottom is on a All-glass or Aqueon 180 Gal tank is? I want to see how close the calculator is. (Also I need to order glass for one for a customer, and want to be sure I'm right with a .5" sides and .5" tempered on the bottom.
Using the calculator for my own is one thing, but I just talked them into making aquariums at work & don't want them to have to pay to clean up a 180 gallon mess.

Thanks in advance,
Barry

Thank you Ryan. That's what the calculator came up with.
