pressure = density x gravitational field strength x height
density of water = 1 Kg per litre
g.f.s = 9.8 Newtons per Kg
height = 5 m
= 1 x 9.8 x 5 = 49.0 Pascals

Pressure = P_atm + density*g*h
Pressure = 1x10^5 + 1000*9.8*5 = 1.49 x 10^5 Pa = 1.49 atm
You need to go down approximately 10 metres to gain an extra atmosphere of pressure

6 bar (atmospheres) absolute pressure
5 bar gauge pressure.
That's good enough for any calculations you're going to do.

...1 metre of fresh water exerts a pressure of 100g/cm²
(1m³ acting on an area of 1m²)
...5m x 100g/cm²
...= 500g/cm²
...= 0.5kg/cm²
