Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2]
Online calculator to convert atmospheres to pascals (atm to Pa) with formulas, examples, and tables. Our conversions provide a quick and easy way to convert between Pressure units.
The average atmospheric pressure on Mars is about 600 Pa. Convert this to atmospheres. Use the same conversion factor, but check to make certain Pascals cancel out so you get an answer in atmospheres.
The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1]
The standard atmosphere (symbol: atm) is a unit of pressure defined as 101 325 Pa. It is sometimes used as a reference pressure or standard pressure. It is approximately equal to Earth's average atmospheric pressure at sea level. [1]
Example - Air pressure at Elevation 10000 m. The air pressure at altitude 10000 m can be calculated as. p = 101325 (1 - 2.25577 10-5 (10000 m))5.25588. = 26436 Pa. = 26.4 kPa. The table below indicates air pressure at elevations below and above sea level.

How to Convert Standard Atmosphere to Pascal. 1 atm = 101325 Pa. 1 Pa = 9.8692326671601E-6 atm. Example: convert 15 atm to Pa: 15 atm = 15 × 101325 Pa = 1519875 Pa.
The standard atmosphere (atm) is approximately equal to the barometric pressure at mean sea level, 101325 Pa. We can use it as a reference value or a unit of atmospheric pressure. Other units of pressure like bar, pound per square inch (psi or lbf/in 2), kilo- and hectopascals (kPa and hPa) are also used to measure barometric pressure.
