Xytras Posted March 12, 2009 Report Share Posted March 12, 2009 Sorry for a dumb question. What exactly ATM stands for and how many feet (or meters) in 1 ATM? Quote Link to comment Share on other sites More sharing options...
krustybrand Posted March 12, 2009 Report Share Posted March 12, 2009 1 atmosphere of pressure = 101kPa (approx) or about 14psi, or about 28ft of water Quote Link to comment Share on other sites More sharing options...

repfreak Posted March 12, 2009 Report Share Posted March 12, 2009 (edited) do remember, you need to discount some depth off cos of friction of the water.. when you swim or move, this create more resistance...

offshore Posted March 12, 2009 Report Share Posted March 12, 2009 To be technically correct- 1 Atm = 14.7 psi= 10M = 33ft! (Salt water) at sea level. Or if you need to go to 4 decimal points, DL this great little conversion program! http://joshmadison.com/article/convert-for-windows/ O/S Quote Link to comment Share on other sites More sharing options...

offshore Posted March 12, 2009 Report Share Posted March 12, 2009 So for lets say watches Davidsen sells that are listed as 3ATM, they should be good to go for showering and general swimming?? Yep! AFTER you have had them tested! Because a watch has a rating on the dial/backcase, doesn't mean it has been tested. If the seller guarantees waterproofing/ depth rating, you have some grounds for hope. But I would still have the watch tested.
