If you mean in the ocean, approximately every 10 meters pressure increases by 1 bar. Assuming you want absolute pressure, at the surface you already have a pressure of approximately 1 bar - the atmospheric pressure. You can base your calculations on that.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}
Bar is a unit used to measure pressure, one bar is the normal atmospheric pressure of the on the surface of the earth, and ten bar is when the pressure is ten times the normal atmospheric pressure on the surface of the earth.
Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.
None! A tank at atmospheric pressure already has an absolute pressure of 1.013 bar.
The 'g' added on to bar means 'gauge', as opposed to bara, meaning 'absolute'. The 'zero' of a normal gauge is normally set at atmospheric pressure (things like tire pressure gauges, water gauges etc.) These gauges will read as "10 bar" but really mean that the absolute pressure is 10 bar + atmospheric pressure (~1.01325 bar). Some gauges however are absolute gauges. These might include weather gauges, or gauges on closed processes. bara = barg + atmospheric pressure
A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute

absolute pressure
53 feet = 16.154 4 meterthe water pressure at 16.154 4 meters = 1.61544 bars + 1 bar of atmospheric pressure makes the absolute pressure = 2.62 bars.
In water, every 10 meters you go down, the pressure increases by 1 bar, approximately. To this you must add the air pressure, which is also approximately 1 bar (depending on whether you want gauge pressure or absolute pressure).
At the Bar was created on 2007-02-02.
Air at 10 celsius and 1 bar(absolute) has density 1.25 kg/m3. By 6 bar do you mean gauge or absolute pressure? To apply a pressure factor you must use absolute, ie the pressure above a vacuum. Normal atmospheric conditions are 1 bar (abs). If you mean 6 bar(abs) the density becomes 6 x 1.25 = 7.5 kg/m3. On the other hand if you mean 6 bar (gauge) this is 7 bar (abs) and the density would be 7 x 1.25 =8.75 kg/m3. Either way, you just divide the weight of air in kg by the density to get the volume.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
