That is an unanserable question. Square foot means an area and for a weight you need at least a volume.
To have weight it must also be a three dimensional unit, things don't have weight in the flatlands. A cubic foot of water weighs 62.42796 Pounds. A cube is the three dimensional version of a two dimensional square, a foot of depth being the difference between a square and a cube.

Why does water pressure increase as you dive deeper?
Water has density and weight. The deeper you dive the more water you have pushing against your body. Think of it like this young padawans: You place a book on your head, no big deal. For every foot that your imagination takes you deeper on a dive add one book. Is that stack of books getting heavy yet? Well if you imagined yourself diving to 130' (FSW) then that stack of books would have weighed in at 130' x .445lbsPerSqInch (book/foot) = 57.85 lbs. 130 being the depth of water in feet salt water (FSW), .445 being the weight of one foot of salt water (one book). The answer is the weight of water (books) measured over the area of one square inch. When you dive, you have the weight of all of the water over you, plus the weight of the earths atmosphere exerting pressure on you (the atmosphere is often neglected, but is of importance). The example of the books that I used is a little innaccurate though. In that example the weight is only being placed on one square inch of your head. In diving however, that force would exist over every square inch of a divers body. You can see how these numbers can add up, and you would think would severely limit the diver. However the body is primarily fluid which is not compressable. Those parts of the body which are compressable (Sinuses, Middle Ear, Respiratory tract, Lungs) are easily equalized with ambient pressure through training and or past experience. If you are wondering how I know what one foot of sea water weighs per square inc h, simply multiply .445lbs (one foot SeaH2o) times 144 (inches in a square foot)= 64 lbs which is the equivalent to the weight of one Cubic foot (ft3) of sea water.
How much does sea water weigh per cubic foot?
The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot. ----------- The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.
How much weight will 1 cu ft displacement of air support?
The weight that 1 cubic foot of air can support depends on the density of the air. At sea level and room temperature, 1 cubic foot of air can support approximately 0.08 pounds. However, this value can vary based on factors such as altitude and temperature.
What describes how salty sea water is?
Sea water is typically around 3.5% salt by weight, or 35 parts per thousand. This salinity can vary based on location and factors like evaporation and precipitation. It is this salt content that gives sea water its characteristic salty taste.
How much pressure does one square foot of water exert?
One square foot of water exerts a pressure of approximately 62.4 pounds per square foot at sea level. This is based on the weight of water, which is about 62.4 pounds per cubic foot. The pressure exerted increases with depth, following the principle that pressure is equal to the weight of the water column above the area.
How many gallons in a cubic foot of sea water?
One cubic foot of sea water contains about 7.5 gallons.
How many pounds does sea water weigh per cubic foot?
About 2.2 pounds of salt in a cubic foot of sea water. There are about 7.48 gallons in a cubic foot and sea water weighs about 8.5 pounds per gallon (63.58 pounds). Sea water is about 3.5 % salt (usually reported as 35 ppt or parts per thousand). So 63.58 x .035 = 2.2 pounds of salt.
Under standard barometric pressure at sea level. What is the unit force per square foot on the surface of the earth?
Under standard barometric pressure at sea level, the pressure is approximately 14.7 pounds per square inch (psi). To convert this to force per square foot, you multiply by the number of square inches in a square foot (144). Therefore, the unit force per square foot is about 2,116.8 pounds (14.7 psi × 144 in²).
A man first swims in seawater then in river water.Compare the weight of seawater and the riverwater displaced by him?
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
How many square mt in a 20 foot sea container?
33.2 cubit meters !!
How many square meters in 20 foot sea container?
33 but usually 28
What does a gallon of sea water weight?
approx. 3,8 kg.
What is the PSI at 1500 feet below sea level?
At 1500 feet below sea level, the pressure increases due to the weight of the water above. Since water exerts approximately 0.43 psi for every foot of depth, the pressure at 1500 feet below sea level would be about 645 psi (1500 feet x 0.43 psi/foot). Adding the atmospheric pressure at sea level, which is about 14.7 psi, the total pressure would be approximately 659 psi.
Why the sailboat floats on the sea?
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
What causes sea pressure?
Sea pressure is caused by the weight of the water above exerting force on a specific point in the ocean. The deeper you go in the ocean, the greater the amount of water above, leading to higher pressure. This pressure is typically measured in units such as pounds per square inch (psi) or atmospheres.
What is the weight of air pushing on an area?
14.7 pounds per square inch at sea level.
