I see that link is adding the pressure due a given depth of water to atmospheric pressure. So even with no water pressure it returns a value 101.3kN/m^2, thats gonna be some thick glass.

There would be probably be 1 atm on the other side of the glass

Do you want to use feet or metres?

Every foot of depth is 62.4 psf more pressure. So 15 feet is 936 psf.

In metric units, would 4.572 metres, so pressure is 46 kPa.

Of course, this is only at the bottom. Pressure varies linearly.

IRStuff, precisely. I just didnt want the OP plugging values into the website and using the figure as the applied load on the glass. Unless of course there is a complete vacuum on the opposite side.
