FAQs

One atmospheric pressure is equal to? ›

One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.

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, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

One atmospheric pressure is related with the Pascal as: 1atm=101325Pa.

Atmospheric pressure is measured by a barometer and barometer's height at normal temperature and pressure at sea level is 76 cm of Hg or 760 mm of mercury, which represents 1 atm.

One atmospheric pressure at sea level is equal to 760 cm of Hg.

One standard atmosphere, which is also referred to as one atmosphere, is equivalent to 101,325 pascals, or newtons of force per square metre (approximately 14.7 pounds per square inch). See also millibar.

An atmosphere is 14.7 PSIA. An atmosphere is the air pressure at sea level. 5 atmospheres is 73.5 PSIA.

1 atm is equal to 101.325 kPa or 14.7 psi, which corresponds to atmospheric pressure at mean sea level. In reality, atmospheric pressure varies quite widely with elevation, weather, temperature and humidity.

1 atm = 101325 Pascals = 760 mm Hg = 760 torr.

The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa.

Is atmospheric pressure always 760? ›

One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, United States, is about half that of Honolulu, Hawai'i, United States. Honolulu is a city at sea level.

1 atm is equal to 760 torr. The atmospheric pressure(atm) is unit of the pressure within the atmosphere of Earth. At sea level the Earth's atmospheric pressure is 1 atm. The torr is an absolute-scale which is unit of pressure.

Atmospheric Pressure and Altitude

At sea level, a mercury column will rise a distance of 760 mm. This atmospheric pressure is reported as 760 mmHg (millimeters of mercury). At higher altitudes, the atmospheric pressure is decreased and so the column of mercury will not rise as high.

The highest sea-level air pressure ever recorded was 1083.8 mb (32.01 in. Hg) in Agata, Siberia on December 31, 1968; produced by a very cold, dense air mass. The lowest sea-level air pressure ever recorded was 870 mb (25.69 in. Hg) measured on October 12, 1979 in the eye of Typhoon Tip as it moved over Guam.

The world record for lowest pressure (at sea level) was 652.5 mmHg recorded inside Typhoon Tip on October 12, 1979, in the western Pacific Ocean. Convert this pressure to each indicated unit.

No, atmospheric pressure decreases with altitude. 1 atm is a unit of measurement of pressure that is equivalent to the pressure exerted by the air at sea level at a temperature of 15 degrees Celsius, and it is averaged.

For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 0.1 kPa.

The standard 'atmosphere' (abbreviated to atm) is a convenient unit for measuring pressures. 1 atm is equal to 101.325 kPa or 14.7 psi, which corresponds to atmospheric pressure at mean sea level.
