4.053bar
That's 1.43× as deep as an open water dive, while the recreational limit is 1.25× deeper. A lungful of surface air would be squeezed to about one 4th of its volume.
What it means
How much pressure is that?
Seawater adds one atmosphere every 10 m; fresh water needs 10.3 m for the same, because it is less dense.
The math
How to convert msw to bar
Depth adds to the atmosphere already above you: ATA = depth in msw ÷ 10 + 1, and in feet ATA = fsw ÷ 33 + 1.
Example: 30 msw = 4.053 bar.
