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
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
A scuba tank typically holds about 11 liters of air at atmospheric pressure.
scuba divers use pressure meter because the deeper down you go the more pressure builds upAdditiona depth gauge or a dive computer
The collective noun is a bubble of scuba divers.
By oxygen tanks - similar to SCUBA divers.
The deeper the diver goes, the higher the pressure is.
Equalising, to stop bleeding out of the ears. Whole scuba suits to ease mobility.

Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.
You can breathe underground by using submersible breathing aparatus similar to scuba gear used by divers.
No, only when it is released into the atmosphere at the ambient pressure.
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
