The smallest unit of atmospheric pressure is the Bar. the next smallest unit of atmospheric pressure is the Pascal, and the largest unit of atmospheric pressure is the Torr.
The unit of pressure in SI is Pascal (equal to 1 N/m2).
In non-SI systems many other units (with multiples and submultiples) exist.
There are several commonly used units for measuring atmospheric pressure. The most common would be atmospheres, Pascals or kilo pascals, and mm Hg (or Torr).
PSI?
Yes, the pressure inside the collection container will be exactly equal to the atmospheric pressure if the water level in the collection container is level with the rest of the water. If the atmospheric pressure is different, then the pressure inside the collection container will be different, and that will affect how you calculate the amount of gas collected. If the pressure is different due to the difference in altitude of the location, or even different weather, the results will be different. Simply measuring the atmospheric pressure with a barometer will allow you correct for any such differences.
A barometer measures atmospheric pressure to determine weather or altitude changes.
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
Because while atmospheric pressure is the greater of the two the vapour pressure of the water can not spontaneously form bubbles (ie boil).
hPa stands for Hectopascal preasure unit this is the international unit for measuring atmospheric or barometric pressure.1 hPa = 100 pascalsStandard atmospheric pressure = 101325 pascals = 1013.25 hPa
the s.i unit of atmospheric pressure is 100000 N/m2
A barometer
The SI unit for pressure is the Pascal.
A pascal is a measurement of pressure, equal to one Newton per square metre. To compare, atmospheric pressure at sea level is 101325 pascals. ■

barometer is used to measuring atmospheric pressure. manometer is used to measuring the pressure of gases.
An instrument for measuring atmospheric pressure, used especially in weather forecasting.
The force of colliding particles
For measuring atmospheric pressure which is used in weather forecasting.
A weather balloon is sent up to gather information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring unit called a radiosonde.
