Just over one atmosphere - of course!
Two atmospheres when you are approximately thirty feet down.

Atmospheric pressure at sea level is usually denoted as 1 atm (1 atmosphere).
"The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa. This value is intended to represent the mean sea level pressure at the latitude of Paris, France,[citation needed] and as a practical matter, approximates the mean sea level pressure for many of the industrialized nations (those with latitudes similar to Paris). One standard atmosphere is standard pressure used for pneumatic fluid power (ISO R554), and in the aerospace (ISO 2533) and petroleum (ISO 5024) industries."

Naturally one atmosphere pressure, equal 1 kilogram/cm²
Under the sea one more every 10 meters depth
