What is standard atmospheric pressure in kPa?

101.325 kPa
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. (For comparison, one pound per square inch equals 6.895 kPa.)

What are standard atmospheric conditions?

A “Standard Atmosphere” can be regarded as an average pressure, temperature and air density for various altitudes. It is defined as having a temperature of 288.15 K (15 oC, 59 oF) at the sea level 0 km geo-potential height and 101325 Pa (1013.25 hPa, 1013.25 mbar, 760 mm Hg, 29.92 in Hg).

What is the pressure at standard temperature and pressure STP?

1 atmosphere
Standard Temperature and Pressure (STP) is defined as 0 degrees Celsius and 1 atmosphere of pressure.

What kPa is low pressure?

Barometers and Air Pressure Average air pressure is around 101.3 kPa. A high pressure system would give you a reading closer to 103.0 kPa and a low pressure system might give you a reading around 100.0 kPa. Look back at our weather maps above.

What is the atmospheric pressure in atm?

Normal atmospheric pressure is 14.7 psi, which means that a column of air one square inch in area rising from the Earth’s atmosphere to space weighs 14.7 pounds. Normal atmospheric pressure is defined as 1 atmosphere. 1 atm = 14.6956 psi = 760 torr.

Is atm a pressure?

Atmospheric pressure, also known as 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; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

What do you mean by standard pressure?

1. standard pressure – a unit of pressure: the pressure that will support a column of mercury 760 mm high at sea level and 0 degrees centigrade. atm, standard atmosphere, atmosphere. pressure unit – a unit measuring force per unit area.
