Toronto pressure fell to 28.40 inches, breaking its record by 0.17. The 956.0 mb (28.23 inHg) barometric pressure measurement recorded in Mount Clemens, Michigan, was the third-lowest non-tropical atmospheric pressure recorded in the mainland United States [6] and the lowest in the Central United States.

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 .

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 ...
MO: April 27: 03:40–03:45 1.5 mi (2.4 km) 100 yd (91 m) A house and numerous outbuildings, including a barn, were severely damaged. The roofs of six other houses were either damaged or completely removed by the tornado.
Inch of mercury (inHg and ″Hg) is a non-SI unit of measurement for pressure. It is used for barometric pressure in weather reports, refrigeration and aviation in the United States. It is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height at the standard acceleration of gravity.

According to the International Standard Atmosphere, at a pressure of 1 atm and a temperature of 15° C, air has a density of approximately 1.225 kilograms per cubic metre (kg/m 3), about 1 ⁄ 1000 the density of liquid water. atmospheric lake A long-lived pool of water vapor. atmospheric model atmospheric pressure (p) Also barometric pressure.
PressureNET was a crowd-sourced reporting network for barometric pressure data. It worked by having many users install it on cell phones having air pressure sensors (barometers) and GPS sensors. Once the location was known from the GPS data, it was able to send messages back to the server with the air pressure for that location on Earth.
