Common Vacuum Measurement Units and Their Conversion
Common units for measuring vacuum levels include Pascal (Pa), millibar (mbar), Torr, and standard atmosphere (atm). Here are the conversion relationships between these units:Pascal (Pa)is the SI unit for pressure.1 Pa = 0.00750062 Torr1 Pa = 0.01 mbar1 Pa = 9.86923×10^-6 atmMillibar (mbar)is another commonly used engineering unit, especially in meteorology.1 mbar = 100 Pa1 mbar = 0.750062 Torr1 mbar = 9.86923×10^-4 atmTorris named after the Italian physicist Evangelista Torricelli and is primarily used to describe low pressures.1 Torr = 133.322 Pa1 Torr = 1.33322 mbar1 Torr = 1/760 atmStandard Atmosphere (atm)is defined as the average atmospheric pressure at sea level at 0°C.1 atm = 101325 Pa1 atm = 1013.25 mbar1 atm = 760 TorrThese conversion factors allow you to switch between different units depending on your application. For example, Pascals might be more common in scientific research, while millibars or Torr may be encountered more frequently in industrial applications. Standard a
