WebThe pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in 2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the … The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI), and is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye (Ba) in the … See more The unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The name pascal was adopted for the SI unit newton per square metre … See more The pascal can be expressed using SI derived units, or alternatively solely SI base units, as: $${\displaystyle {\rm {1~Pa=1~{\frac {N}{m^{2}}}=1~{\frac {kg}{m{\cdot }s^{2}}}=1~{\frac {J}{m^{3}}}}}}$$ where N is the See more • Atmospheric pressure which gives the usage of the hbar and the mbar • Centimetre of water • Meteorology See more The unit of measurement called an atmosphere or a standard atmosphere (atm) is 101325 Pa (101.325 kPa).
