P=rho*g*h
P= pressure
rho= density = 1000 kg/m^3 at about 20C
g= gravitational constant on earth at sea level = 9.81 m/s^2
h= height
P=1 bar=1x10^5 Pascals = 1x10^5 N/m^2 (based on the definition of the Pascal unit)
since by definition 1 Newton= 1 kg*m/s^2
1x10^5 N/m^2= 1x10^5 kg*m^2/(m^3*s)= 1x10^5 kg/(m^2*s)
1x10^5 kg/(m^2*s) = 1000 kg/m^3 *9.81m/s^2 * h
solving for h yields:
h= 1x10^5/(1000*9.81)= 10.19367 meters
This value might vary slightly due to the affect of temperature on the density of water.
Pounds per Square Inch or Psi is a unit of pressure or stress. 1 bar is equal to 14.50377 Psi.
1 bar = 14.5 PSI
1 bar is 14.5038 psi. Scroll down to related links and look at "Conversion of pressure or stress units".
If an instrument is indicating a wrong parameter instead of actual. Say the actual pressure is 1 bar but the instrument is reading 1.5 bar is an example of instrumental error.
The micron is 1 x 10-6 meters, so 5 microns is 5 x 10-6 meters. This is also 0.005 millimeters, or 0.000197 inches.

Water pressure increases by approximately 1 bar for every 10 meters of depth in freshwater. At a depth of 10 meters, the water pressure would be about 1 bar, in addition to the atmospheric pressure at the surface, which is roughly 1 bar as well. Therefore, the total pressure at 10 meters depth would be about 2 bars.
90 meters. Every 10 meters, the pressure increases by approximately 1 bar, to this, you have to add the atmospheric pressure, which is also approximate 1 bar.
10.20 meters in depth
1 Pa = 1 N/m2 = 10−5 bar = 10.197×10−6 at = 9.8692×10−6 atm,
The recommended water pressure is 0.5 to 1 bar
A depth of about 33 feet (10 meters) in sea water is required for the pressure to reach 1 bar. This is because each meter of water exerts a pressure of approximately 0.1 bar.
Pressure at a given depth of water can be calculated using a formula like, "#1 #1kgf/cm2." Therefore, water pressure at 2000 meters below sea level will be around 1.2 bar.
A depth of approximately 10 meters is required in sea water for 1 bar pressure. This is because each meter of water depth exerts a pressure of approximately 0.1 bar due to the weight of the water above it.
12.6 meters 0.1 bar is gained for every meter.
10.332 metres.
