Those are incompatible (non-convertable) units: Feet is a measure of length, atmospheres is a measure of pressure.
Two atmospheres is 67.8 feet of water.
To convert feet to atmospheres, we first need to convert feet to meters (1 foot is approximately 0.3048 meters). Therefore, 6.6 feet is about 2.012 meters. The pressure at sea level is approximately 101.3 kPa, which is equivalent to 1 atmosphere. Given that 2.012 meters of water exerts about 0.2 atmospheres of pressure, 6.6 feet is approximately 0.2 atmospheres.

10 feet = 3.333 yards and 120 inches.
10 atmospheres is about 340 feet of water depth.
Two atmospheres is 67.8 feet of water.
660 feet
It means 10 atmospheres. This usually indicates a watch will remain waterproof to a depth of 10 atmospheres or about 340 feet of water.
1,000atm is about 33,900 feet of water depth.
One foot is a unit of distance. One atmosphere is a unit of pressure (force per unit area). 10 atmospheres is equivalent to about 21,162 lb/ft^2 (pounds per square foot). At 339 feet under water, the pressure is approximately 10 atmospheres (assuming water density is 1000 kg/m^3).
3 atmospheres
About 335 feet.
4 atmospheres is about 135.6 feet of water depth.
50 feet of water is about 1.475 atmospheres.
990 ftAdditionApproximately 958 feet for 29 atmospheres of sea water and 1 atmosphere of surface air pressure.
