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.)

What does the abbreviation ATM on a waterproof watch stand for?
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.
What does 10 ATM mean on a wrist watch?
It means 10 atmospheres. This usually indicates a watch will remain waterproof to a depth of 10 atmospheres or about 340 feet of water.
What is the water pressure in depth of 1500m?
you have to do the density of the water times by the weight times by the height
State how the pressure in liquid depens on the depth of the liquid?
Density of liquid (kg/m3) * gravitational constant (m/s2) * depth (m) = (extra) pressure under liquid (Pa) Density of water = 998 (kg/m3) gravitational constant = 9.81 (m/s2) 1,000 ATM = 1.013*10-5 Pa Raw formula: pressure under water = 1 (ATM) per 10 (m) depth
What is gauge pressure at a depth of 100 m in water?
About 160 psi or 11 atm
How deep under water is 5 ATM?
5 atm indicates a depth of about 132 feet.
What is the meaning of ATM on a wristwatch?
"ATM" stands for "atmospheres," and the ATM rating on your wristwatch is the depth before the sea surface at which you can safely wear your watch. Most watches are rated between 1 ATM and 10 ATM. For more information, see the Related Link.
How deep is 100 ATM?
Every 10 meters deep, the pressure increases by one atmosphere, approximately. Therefore, at 90 meters depth you would have, approximately, a pressure of 10 atm. (that is absolute pressure).Every 10 meters deep, the pressure increases by one atmosphere, approximately. Therefore, at 90 meters depth you would have, approximately, a pressure of 10 atm.

What does 3 ATM mean on a wrist watch?
The term "atm" means "atmosphere" It's a term used to measure pressure. One atmosphere is the atmospheric air pressure at sea level. On a watch it is a measure of water resistance. Under water the pressure increases by one atmosphere for every 10 metres of depth. So "10 atm" on a watch means it is water resistant to 100 metres. "30 atm" is water resistant to 300 metres. http://en.wikipedia.org/wiki/Atmospheric_pressure
What is the water pressure at 3 kilometers?
At a depth of 3km, water pressure is 298.6 atmospheres (atm) or 4,388.37 pounds per square inch (psi)
According to the phase diagram for H2O what happens to the phases of water at 0 degC as the pressure is increased from 0 ATM to 10 ATM?
water changes from a gas to a solid to a liquid
What are the pressure changes in scuba diving?
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).
