what is the standard pressure
Introduction: Standard Pressure
In 17th century, some innovative scientists invented the force that acts on the area and they named this force as Standard Atmospheric Pressure. These scientists determined this important fact during their journey to Mt.McKinley. One of the scientists named Evangelista Torricelli noticed this standard pressure first time and he was the first person to introduce such consternating facts (related to Pressure). Initially this pressure was called as Atmospheric pressure because they think that this is the force exerted by the atmosphere on all humans.Is this topic Formula of Ionic Compounds hard for you?

What Standard Pressure means
Standard Pressure is nothing, but a unit widely used to determine the value of pressure. The values for Standard Pressure are 1 atm or 101325 Nm-2 or 760 mm Hg or 101.325 kPa. In simple words, pressure is defined as the force acting per unit area and standard pressure means those values, which are taken, as standard values i.e. which cannot be changed in any circumstances. In the year 1999, IUPAC (International Union of Pure and Applied Chemistry) proposed that in order to determine the properties of compounds the value of standard pressure will be taken as 100 kPa or 29.53 Hg instead of taking 101.325 kPa. When combined with Standard temperature, standard pressure is written as STP and the values of STP are based as per the conditions occurring in the atmosphere depending on the sea level. Moreover, these standard values of either temperature or pressure are of much importance to our scientists, chemists and other researchers.

Facts related to Standard Pressure
Some important facts related to Standard Pressure are as follows:
Standard Pressure is always taken with reference to 760 mm in mercury barometer.
In many cases, we can use 29.9 inches of Hg instead of using 760 mm Hg value.
Standard Pressure also includes one more value, which is 14.7 lb (pounds) per inch. This value of pressure is found when a certain column of air exerts pressure over an area.
Standard Pressure is the reference pressure and its widely used unit is 1 atm.
Conclusion
Standard Pressure is related with the pressure at the mean sea level exerted by the atmosphere of Earth. This Standard Pressure is always taken as a reference while calculating the standard values.
