Atmospheric pressure is air pressure due solely to the weight of the air above you in the atmosphere. It is typically around $10^5\ \mathrm{N/m^2}$ on Earth, but can vary with altitude and weather. It is just a "natural," ubiquitous special case of air pressure in physical situations taking place inside an atmosphere. Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere over the barometer.

This value corresponds approximately to the mean sea-level atmospheric pressure on Earth. Note that "high barometric pressure" is a relative term. At high altitudes, where the pressure can be much lower, the aforementioned pressure values …The barometer rises highest of all for north and east winds; for all other winds it sinks. The barometer UNSETTLED (unsteady pressure) If the motion of the mercury be unsettled, expect unsettled weather. If it stands at "MUCH RAIN" and rises to "CHANGEABLE" expect fair weather of short continuance.At standard sea level, the barometric pressure equals 760 mm (29.92 inch) of mercury. A rise in barometric pressure is generally considered an improvement in the weather, while a fall in barometric pressure may mean worsening weather. A fall in barometric pressure can affect health in various ways.Air pressure, also known as atmospheric or barometric pressure, is the force applied by air molecules [1] as they press down on the earth and all other surfaces.

On the other hand, during fall and winter, the barometric pressure increases, reaching levels of 1015-1030 millibars. These pressure changes are influenced by weather patterns and the movement of air masses in the region.Mar 27, 2024 · 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. What is atmospheric pressure? Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
