pressure
The SI unit of pressure is the pascal. 1 pascal is rather small, so normal atmospheric pressure on Earth is about 100 kilopascal.However, any pressure units can be used; some that have been are psi (pounds per square inch), bar (defined so that average air pressure = 1 bar), inches (or millimeters) of mercury (the pressure exerted by a column of liquid mercury of that height)or torr (1 torr = 1 mmHg);.
Any pressure is always expressed in (a unit of force) divided by (a unit of area). Air pressure is most commonly described in one of the following units: -- torr (millimeter of Mercury) -- pound per square inch -- Pascal (newton per square meter) -- bar (100,000 pascals)
The SI unit is the pascal, equal to one newton per square meter. A bar is exactly 100,000 pascal. An atmosphere is approximately equal to a bar. Torr means more or less the same as mmHg, and refers to the pressure caused by a liquid column of mercury (Hg).
The standard measure for pressure is the Pascal (Pa). It is defined as one Newton per square meter (N/m^2). Other commonly used units for pressure include atmospheres (atm), bar, and pounds per square inch (psi).
Chemistry uses both the metric system and the International System (SI) units of measurements. Air pressure equations are measured in atmospheres (ATM) and Pascal's (Pa) for physical chemistry.
Pressure is a measure of force per area. The SI unit of pressure is a Pascal (Pa) which is equivalent to a Newton per meter squared (N/m2).

Yes 1 bar = 100 kilopascal = 730,062 torr = 1,01972 kgf/cm2
Pressure is often measure in units of force per area. In the standard system of units, the SI, that would be Newton / meter2 - this unit is also called Pascal. Other commonly used units are bar (equal 100,000 Pascal), and atmosphere (the atmospheric pressure under standard conditions - close to one bar).
Any pressure is always expressed in (a unit of force) divided by (a unit of area). Air pressure is most commonly described in one of the following units: -- torr (millimeter of Mercury) -- pound per square inch -- Pascal (newton per square meter) -- bar (100,000 pascals)
1 torr is equal to 0.001333 bars, so 331 tr = 0.441296 bar
The SI unit is the pascal, equal to one newton per square meter. A bar is exactly 100,000 pascal. An atmosphere is approximately equal to a bar. Torr means more or less the same as mmHg, and refers to the pressure caused by a liquid column of mercury (Hg).
The unit of measuring atmospheric pressure is called a "pascal" (Pa), which is equivalent to one newton of force applied over one square meter. Another common unit used is the "bar", where 1 bar is equal to 100,000 pascals.
1 atm = 760 mm Hg = 760 torr = 101,325 kPa = 1,01325 bar
1 Torr = 0.00133322 bar 1 Torr = 133.322 Pa 1 Torr = 0.00131578584 ATM 1 Torr = 1 mmHg
The international standard unit for measuring pressure is the pascal. 1 pascal = 1 newton / square meter. A unit commonly used is the bar; 1 bar = 100,000 pascal; and that's the approximate air pressure at sea level. Older units that are still sometimes used include mmHg (millimeter mercury).
