Pressure "landmarks": typical pressures reached by large-volume presses are up to 30–40 GPa, pressures that can be generated inside diamond anvil cells are ~1000 GPa, [2] pressure in the center of the Earth is 364 GPa, and highest pressures ever achieved in shock waves are over 100,000 GPa. [3]
[268] [269] With the weather station at Zürichberg reporting its highest ever value since the station was established in 1949. [ 270 ] Other high pressures in Switzerland are given as 3–4 March 1990 at Zurich Airport of >1047 hPa [ 271 ] and 29 January 1989 at Schaffhausen of 1047.2 hPa, which was the highest pressure in the country since ...
The most intense storm by lowest pressure and peak 10-minute sustained winds was Typhoon Tip, which was also the most intense tropical cyclone ever recorded in terms of minimum central pressure. Storms with a minimum pressure of 899 hPa (26.55 inHg) or less are listed. Storm information was less reliably documented and recorded before 1950. [6]

Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

The Pollutant Standards Index (PSI) is a type of air quality index used in Singapore, which is a number used to indicate the level of pollutants in air. Initially PSI was based on five air pollutants, but since 1 April 2014 it has also included fine particulate matter (PM 2.5 ).
