"ATM" stands for ATMospheres and the number before it, refers to the number of atmospheres of pressure the watch will withstand before leaking. At sea level we are all subjected to one atmosphere of pressure, because we have one atmosphere of air above us pressing down. For every 33 feet (10 metres) underwater you go, the pressure increases by 1 atmosphere. Therefore, at 33 feet underwater the pressure is 2 atmospheres (2 ATM), at 66 feet underwater the pressure is 3 atmospheres (3 ATM), etc. So 5 ATM is equivalent to 132 feet (40 metres) underwater. In conclusion, the ATM rating of a watch is the number of atmospheres of pressure the watch will withstand before breaking/leaking. To convert ATM 's into the depth rating in metres just subtract 1 and multiply by 10. eg: 5 ATM = (5 - 1)*10 = 40 metres.

Using dimensional analysis (unit analysis):5 pa * [(1 atm) / (101325 pa)] * [(760 mm Hg) / (1 atm)] * [ (1 inch) / (25.4 mm)] = 0.00148 inches Hg

Rule of thumb is that each 33 feet adds an atmosphere of pressure. At sea level, 1 atmosphere, at 33 feet, 2 atmospheres, at 66 feet, 3 atmospheres, at 99 feet, 4 atmospheres, and at 132 feet, 5 atmospheres. A diver at 132 feet has 5 atmospheres of pressure on him.

Actually, 5 ATM can either be 132 feet or 165 feet. We all have 1 ATM above us (the air/sky/atmosphere) that creates a constant pressure. Sooo.. 1 ATM + 4 ATM (33ft per ATM) = 132 feet underwater. However, if you actually mean 5 ATM UNDERWATER, then it would be 6 ATM (1 ATM + 5 ATM underwater) for the equation which would equal 165 feet. Hope this helps!

No, at least they should be 10atm or 100m/33ft 5 ATM you can use it in the shower
howdy, use a pocketwatch like i do, my wrists are 13-5 inches around!

5 atm indicates a depth of about 132 feet.
Watch out for trees.
The total pressure will be 5 atm and the partial pressure of gas 1 will be 2 atm and the partial pressure of gas 2 will be 3 atm.

Yes. It's rated for static pressures up to a shower (though it's still not recommended to actually shower with it on as depending on the watchband type and materials used in your cleaning products, can be harmful to the watch's water-resisting components).
Most of the time it has to do with an inmate or a jailer. For more info check here. http://en.wikipedia.org/wiki/Five_Dots_Tattoo
