(B) A modern aneroid barometer in the form of a dial is used by meteorologists ...Air pressure is the force exerted by the atmospheric air on the surface of the planet. It changes with altitude and temperature. The higher the elevation, the smaller is the mass of the air overlying the ground. Also, atmospheric pressure increases with the increase in temperature. The units of pressure are Pascals (symbol: Pa).1 kPa = 1000 Pa = 0.01 bar. Multiply the pressure in kPa with 0.01 bar/kPa to convert kilopascals to bars: pressure in bar = 210 kPa × 0.01 bar/kPa = 2.1 bar. Verify the result with our barometric pressure conversion tool. Use this barometric pressure conversion tool when converting atmospheric pressure to a different unit.6. Balloon in a Bottle: Air Pressure Experiment.

In meteorology, air pressure is most often expressed in "millibars:" each millibar is exactly one dyne (gm-cm/sec^2) per square centimeter in the c.g.s. system of units. A barometric pressure headache is a head pain or discomfort triggered by changes in the weight or force of the air on earth. Experiencing weather conditions, like thunderstorms, or moving at significant levels above sea level, such as mountain climbing or air travel, are potential causes of these headaches. The weight of air above a given area on Earth’s surface is called atmospheric pressure. It is an important factor influencing Earth’s weather and climate. Atmospheric pressure can be measured with an instrument called a barometer and thus is also known as barometric pressure. It is usually measured in millibars (mb) or kilopascals (kPa).
