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.
3 atmospheres
751.5 mmHg = 0.9888 atmospheres
For each 33 feet of depth in water the pressure increases approximately 1 atmosphere. So 100 meters is approximately 330 ft divide by 33 equals 10 atmosphere.
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.
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.
This value is 0,9657895 atmospheres.
5,000 feet of water depth is about 147.5 atmospheres.
