Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of air.
Air pressure above sea level can be calculated as
p = 101325 (1 - 2.25577 10-5 h)5.25588
where
p = air pressure (Pa)
h = altitude above sea level (m) The standard atmosphere is a unit of pressure and is defined as being equal to 101.325 kPa.

What is the air pressure at sea level called?
Sea level pressure, sometimes as mean sea level pressure.
How much air pressure is on you if i'm below sea level?
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
Where is the air pressure greater-at sea level or on a mountaintop?
Air pressure is Greater at sea level.Atmospheric pressure is higher at sea level. There is more atmosphere on top of the observer at that point, so the pressure is higher.
Where is air pressure weakest?
The lower you go into the sea level, the greater the air pressure. The higher you go above the sea level, the lower the air pressure.
Where is there more air pressure sea level or at the top of a mountain?
At sea level

How much air pressure is on you if i'm below sea level?
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
Where is air pressure the greatest?
The air pressure is greatest at sea level.
The measurement of air pressure at sea level is called?
Sea level pressure.
Where is the air pressure greater-at sea level or on a mountaintop?
Air pressure is Greater at sea level.Atmospheric pressure is higher at sea level. There is more atmosphere on top of the observer at that point, so the pressure is higher.
Where is air pressure weakest?
The lower you go into the sea level, the greater the air pressure. The higher you go above the sea level, the lower the air pressure.
Where is the air pressure the greatest at sea level or on a mountain?
sea level
Would you expect the air pressure in a valley that's below sea level to be higher or lower than air pressure at sea level?
The air pressure must be higher in a valley below "sea level". The air mass above this point is more than at sea level.
Where is there more air pressure sea level or at the top of a mountain?
At sea level
Where is air pressure the highest sea level or atop a mountain?
Sea level
What happens to air pressure when you move upward away from sea level?
The farther up away you are from sea level the less air pressure there is.
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
