Standard Day Conditions are:
29.92 inches of Mercury which equals 14.69 PSI or 1013.2 Milibars
at 15 degrees Celsius or 59 degrees Fahrenheit
with zero percent humidity at sea level.
Standard atmosphere is 760 mm of mercury at sea level, zero degrees Celsius with zero percent humidity.
note: kPa = kilopascals, which is still an SI unit
101.3 kPa or 760 mmHg (millimeters of Mercury) or 760 torr.
atmosphere refers to the thin layer of gases above the earth's surface through which living things earn their life
14.696 psi.
760 mmHg
101.325 kilopascals.
The standard sea level pressure of Earth's atmosphere - a pressure of 1 Bar or one "atmosphere".
151.98 kPa is about 1.5 ATM
The amount of pressure the atmosphere has varies from location to location. The internationally accepted standard atmospheric pressure is approximately 14.696 pounds per square inch (psi). This pressure is that which is measured for the altitude and location of Paris, France and is used in relevance.
It is mainly determined by the pressure and composition of the atmosphere as well as how far away from the earth it is.
101.325 kilopascals.
Atmospheric pressure is measured in "Standard Atmosphere" (atm). 1 atm is equivalent to the 101.325kPa (Kilo Pascals) On average is of the weight of a column of air, one square centimeter, measured from sea level to to the top of the atmosphere.
The standard sea level pressure of Earth's atmosphere - a pressure of 1 Bar or one "atmosphere".
1 standard atmosphere (at) = 760 torr = 9,8692.10e-6 Pa = 0,98692 bar
Standard temperature and pressure conditions are: Temp: 273K or 0°C Pressure: 100k or 1 bar STP is 273K or 0oC and 1 bar or 100kPa
151.98 kPa is about 1.5 ATM
101.325 kPa is equivalent to one atmosphere of pressure, or 760 mm Hg. It is a very useful conversion factor.
Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute
One atmosphere is 14.7 psi (rounded)
The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa. It is equivalent to 760 mmHg (torr) or 29.92 inHg. One standard atmosphere is standard pressure used for pneumatic fluid power (ISO R554), and in the aerospace (ISO 2533) and petroleum (ISO 5024) industries.Go Here: http://en.wikipedia.org/wiki/Atmospheric_pressure
At STP (standard temperature and pressure) it is a gas. It can be made to be a liquid or gas by adjusting the temperature and pressure around it, but at room temperature and one atmosphere of pressure (sea level) it is a gas.
