There is 1 ATM at sea level, so 0 (zero) feet of water.
If you need to calculate other pressures or depths:

ATM is the abbreviation for atmosphere's, which is a measurement of pressure. 1 ATM = 14.696 PSI 30 ATM = 440.88 PSI (440.88 pounds)/1 square inch = (40.88 pounds)/(1/144)square feet 63486.72 pounds per square foot. So 30 atmospheres is equal approximately to 63486.72 pounds per square foot.
101.3 kPa = 1 ATM

ATM is the abbreviation of atmosphere which is used for nautical measurements 1ATM is equivalent to 33 feet so Ur wrist watch is resistant to 33ft wile diving..
1 ATM equals 33.9 feet so rounded up to 34 feet your 10 ATM's equal 340 feet. HTH.
990 ftAdditionApproximately 958 feet for 29 atmospheres of sea water and 1 atmosphere of surface air pressure.
ATM is the depth by which water resistance is measured on a watch. ATM stands for Atmospheres. 1 atmosphere is equivalent to appx. 33 feet depth in water. So if a watch is 3 ATM = 100 ft. water resistant.
Depends on atmospheric pressure. At 1 ATM this is 10.3m (33 feet)

1 atm
About 10 feet of water equals 1 atmosphere or about 14.7 psi. The entire weight of the atmosphere exerts 1 atm of pressure at ground level therefore about 10 feet of water spread evenly across the face if the earth would weigh the same as all of the gases on the atmosphere.
The pressure in ATM at the normal boiling point of water is 1 ATM.
Every 10 metres of water adds 1 ATM, so a depth of 10 metres is 2 ATM (the atmosphere of pressure at the surface plus the pressure of 10 metres of water). 10 ATM is reached at 90 metres, or approximately 295 feet (10 metres is approximately 33 feet). (The 1atm/10m is true for salt water at 15C; actual pressure/depth depends on water - fresh Vs salt - and temperature, but 1atm/10m is a good guideline for most purposes.)
101.3 kPa = 1 ATM
water changes from a gas to a solid to a liquid
Let's take a moment to define some terms. The typical value used to represent air pressure at sea level is 14.7 pounds per square inch or 14.7 PSIg. You can think of 14.7 pounds as the "weight" of the entire column above a one square inch surface. For convenience, this pressure is also termed one "Atmosphere" or atm. The formal definition of one atm is 1.01325 x 105 pascals. Think of one atm as "about 15 PSIg". Unlike air, water has the property of not being compressible. The means a given volume of water "weighs" the same, regardless of depth. Accordingly, water pressure increases linearly with depth. It increases about 1/10 atm for each foot of sea water, or 1 atm every 33 feet. A diver at 33 feet of sea water is under a total pressure of 2 atm - one atm of air and one atm of water. At 66 feet, the total pressure is 3 atm, and so on. At 660 feet, the total pressure is 21 atm (660/33) of water plus one of air).
