Pascals (1 Pascal = 1Newton/m^2)
1000 Pascals = 1 kiloPascal
Most of weather stations and such will display air pressure in kiloPascals (kPa) unless you're one of them's United States folks, in which case it may be displayed in pounds per square inch (psi). I don't know.
Atmospheric pressure is measure in one of three things.
Atmospheres (ATM), kilopascals (kPa) or millimeters of Mercury (mmHg)
1.000 ATM = 101.3 kPa = 760 mmHg.
Pascal
Usual measuring unit is mm of Hg.Inch of Hg,Pa(pascal unit),kPa(kilo pascal) and psi units are also units of atmospheric pressure.
STP is equal to 29.92 inches of mercury, 14 psi, 760 mm of mercury
760 mmHg
67-78 mm Hg
760mm
If the ice is free of impurities and the pressure is standard atmospheric pressure, then it melts at zero
The pascal (Pa) is the standard unit of pressure.
It is an definition by the international organization. When the temperature is 15 centigrade degree. To measure the atmospheric pressure is 1013.25 hundred pascals.
A standard atmosphere, denoted by the symbol atm, is a unit of pressure measurement equal to 101,325 pascals, 760 millimeters of mercury, 29.9212 inches of mercury, or 14.696 pounds per square inch. The relationship between atmospheric pressure change and height above the earth's surface
The surface of the earth is at the bottom of an atmospheric sea. The standard atmospheric pressure po is measured in various units: 1 atmosphere = 760 mmHg = 29.92 inHg = 14.7 lb/in² = 101325 Pa = 1013.25 mbar = 1013.25 hPa.
14.7 psia represents standard atmospheric pressure, or 1 atm. PSIA is just psi with atmospheric pressure taken into account also.
a term that indicates a combined measurement of standard atmospheric pressure and room temperature. A+
1 atm (standard atmospheric pressure) is 101,325 kPa.
1 atm (standard atmospheric pressure) is 101,325 kPa.
It is mean atmospheric pressure at sea level.
ATM stands for atmosphere, such as in atmospheric pressure.
A barometer is an instrument used to measure the atmospheric pressure. It does so by comparing the atmospheric pressure with a predefined standard pressure.

The atmosphere has numerous measurable properties, including pressure, temperature, humidity, velocity. Each of these is measured by a different instrument. Pressure is measured by a barometer, temperature is measured by a thermometer, etc.That would be a barometer. I assume you are referring to atmospheric pressure.
Standard conditions, or standard temperature and pressure (STP) is the atmospheric pressure at sea level with temperature at zero degrees Celsius (273.15 Kelvin).
