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 most intense storm in terms of barometric pressure and maximum sustained winds is Hurricane Harvey in 2017, which also caused the most fatalities and damages, with $125 billion in Texas. [ nb 1 ] The first storm to impact the state during the period is Hurricane Allen in August 1980, with the most recent being Hurricane Beryl in July 2024.
With a barometric pressure of 922 hPa (27.23 inHg) at the time of landfall in Florida, Andrew is the sixth most-intense hurricane to strike the United States. Several hours later, the hurricane emerged over the Gulf of Mexico at Category 4 strength, with the Gulf Coast of the United States in its dangerous path.
A rare winter storm is expected to bring heavy snow, sleet and freezing rain to Florida, Texas and other parts of the South next week. While some uncertainty remains over exactly how much snow ...
Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. [ 1 ] The U.S. Standard Atmosphere is a static atmospheric model of how the pressure , temperature , density , and viscosity of the Earth's atmosphere change ...
The most intense storm in terms of both barometric pressure and maximum sustained winds was Hurricane Carla in 1961, which also caused the most fatalities, with 46 deaths. [nb 1] The first storm to impact the state during the period was Tropical Storm How in October 1950, with the latest being Tropical Depression Twenty in September 1979. [1]
The solution is given by the barometric formula. Air density must be calculated in order to solve for the pressure, and is used in calculating dynamic pressure for moving vehicles. Dynamic viscosity is an empirical function of temperature, and kinematic viscosity is calculated by dividing dynamic viscosity by the density.
