32.12 psi and 1013.2 millibars
Convention sets it at 1 mb at the top, and generally about 50-90 mb at the bottom.
It is not know for certain. One thing that is known is that the pressure is low inside a tornado. The intensity of a tornado is largely determined by the pressure deficit, meaning how much lower the pressure inside the tornado than its surroundings. It is estimated, that a strong tornado will have a pressure deficit of at least 25 millibars, so that if the pressure surrounding the tornado is 950 millibars, the core pressure will be 925 millibars. A violent tornado may have a pressure deficit of over 100 millibars.
The standard atmospheric pressure is the air pressure of 101325 pascals (Pa) or 101.325 kilopascals (kPa) (1013.25 millibars), exerted by a 760 millimeter (29.92 inches) column of mercury at sea level at a temperature of 0 degrees Celsius.
That depends upon the air pressure around the water. At one atmosphere, the average air pressure at sea level on Earth, it would be a gas.

Millibars is spelled as "millibars." It is a unit of measurement used in meteorology to measure atmospheric pressure. One millibar is equal to one thousandth of a bar, which is approximately equal to the average atmospheric pressure at sea level.
Standard pressure is the pressure exerted by a column of mercury exactly 760 mm high. This is called one atmosphere and is approximately the average pressure at sea level.
The standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch. It is less than half the pressure in automobile tires.

On average, 29.92 inches of mercury relative to sea level.
Earth doesn't have one continuous, constant atmospheric pressure, it varies both spatialy and temporally. Assuming you're talking about the atmospheric pressure at the Earth's surface, the "standard" atmospheric pressure is 1000 millibars (mb), however pressures can range anywhere from ~875 mb (in intense low pressure areas such as the center of tropical cyclones) to ~1080mb.
Venus has a very thick atmosphere of Carbon dioxide. Its average surface pressure is a crushing 93 bar, or 93 times that of Earths
In the room will usually be the same as the outside atmospheric pressure. The standard atmosphere is defined as being 101325 pascals = 101.325 kPa.
