The absolute pressure - pabs - is measured relative to the absolute zero pressure - the pressure that would occur at absolute vacuum.

Temperature (ºF) Relative … By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. ton force/square inch, ton force/square meter and torr (mmHg)"The most frequently used units of pressure are pascal (Pa), kilopascal (kPa), megapascal (MPa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar.An atmosphere (atm) equals to the air pressure at the sea level at a temperature of 15 Celsius.Bar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure.Inch of Mercury (inHg) is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height.Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre).Pascal is the unit of pressure in the metric system and is equal to 1 newton per square meter.Psi is a pressure unit and equals to the force of one pound applied to one square inch. Atmospheric pressure is expressed in several different systems of units: millimetres (or inches) of mercury, pounds per square inch (psi), dynes per square centimetre, millibars (mb), standard atmospheres, or kilopascals.Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 10 3 dynes per square …

However, over cold air the decrease in pressure can be much steeper because its density is greater than warmer air.
