How barometric pressure is measured
WebThis happens because the mass of air in the bottle is fixed, so an increase in atmospheric pressure reduces its volume and vice versa. You can use any fluid, but water will evaporate into the bottle and air in the bottle will dissolve in the water. I suggested motor oil because it's vapour pressure is low and air isn't very soluble in it. Atmospheric air pressure where standard atmospheric pressure is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about 14.7 pounds per square inch. Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient. After the advent of SI units, some meteorologists began using
