The method is the same, but the formula differs depending on whether you want it in meters or feet.
The easy method in feet is to add .3 atmospheres (ata) every 10 feet (or every 3 meters) and then add a surface atmosphere, so 20 feet would be:
[(.3 x 2) +1] = 1.6 ata
The simple formula for feet is: (Depth + 33)/33
For meters it is: (Depth +10)/10

Atmospheric pressure is the amount of force the column of air above you is exerting on you. At sea level you are considered to be at one atmosphere of pressure. Because Air is affected by the un-even heating of the Earth and the Earth's rotation we get high and low pressure systems that create different types of weather. Air will try and even it's self out and will always move from areas of high pressure to areas of low pressure.
In Scuba diving you experience water pressure instead of air pressure. At 10 meters (33 feet) you experience 2 atmospheres of pressure. This will increase by about 4.4 psi for every 10 feet or so depending on the water (fresh or salt ?)

Mixture of gases for scuba diving tanks compared to normal atmospheric air?
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
What do scuba divers use to tell how far down they are?
scuba divers use pressure meter because the deeper down you go the more pressure builds upAdditiona depth gauge or a dive computer
What is the collective noun of scuba divers?
The collective noun is a bubble of scuba divers.
If there is no oxygen on the moon then how does the man in the moon breathe?
By oxygen tanks - similar to SCUBA divers.
Why do deep sea divers require greater protection than scuba divers?
The deeper the diver goes, the higher the pressure is.
How do scuba divers protect themselves from the damaging effects of pressure?
Equalising, to stop bleeding out of the ears. Whole scuba suits to ease mobility.
Who uses a scuba-suit?
Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.
Who can get bends?
scuba divers
How do you breathe underground?
You can breathe underground by using submersible breathing aparatus similar to scuba gear used by divers.
Does atmospheric pressure have any effect on the oxygen level in the scuba tank?
No, only when it is released into the atmosphere at the ambient pressure.
Before a diver dives will he will take a deep breath or hyperventilate?
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
How do scuba divers move?
They swim
