Pressure is the force per unit area applied on a surface. Fluid pressure is the pressure at some point within a fluid environment (liquid or gaseous). If the fluid is not moving quickly, then the term is hydrostatic pressure for liquids, and barometric pressure for gases. If the gas pressure being measured is the air on a planet – or in an artificial environment – then the term may be more specifically atmospheric pressure.

Units of measurementEdit

Comparative list of pressuresEdit

  • 4.93 atm, 5,000 mbar, 500 kPa, 72.5 psi – Capped deuterium well heads are under 5,000 millibars of pressure. (ENT: "Marauders")
  • 0.89 atm, 900 mbar, 90 kPa, 13.1 psi – The pressure encountered from the leading edge of shock waves encountered by USS Voyager following the explosion of a supernova were over 90 kilopascals – more than 30% higher than predicted. (VOY: "The Q and the Grey")
  • 0.790 atm, 800 mbar, 80 kPa, 11.6 psi – The atmosphere at the surface of an unnamed planet which was home to a species of rock creatures was recorded at 800 millibars. (TAS: "Mudd's Passion")
  • 0.21 atm, 210 mbar, 21 kPa, 3.0 psi
    0.25 atm, 250 mbar, 25 kPa, 3.6 psi – Warp core pressures aboard Starfleet ships were measured in kilopascals. Upon being pulled into the Delta Quadrant, Voyager's warp core pressure was down to 21 kilopascals. Upon unlocking the magnetic interlocks, they were able to increase it to a stable rate of 25 kilopascals. (VOY: "Caretaker")
  • 0.113 atm, 114 mbar, 11.4 kPa, 1.7 psi
    0.092 atm, 93 mbar, 9.3 kPa, 1.3 psi – The computer warned Tom Paris that his space suit was leaking, informing him that the oxygen level was dropping from 114 millibars to 93 millibars before B'Elanna Torres connected to his suit to share her oxygen. (VOY: "Day of Honor")
  • 0.103 atm, 104 mbar, 10.4 kPa, 1.5 psi
    0.086 atm, 87 mbar, 8.7 kPa, 1.3 psi
    0.070 atm, 71 mbar, 7.1 kPa, 1.0 psi – While Paris and Torres shared their oxygen, the level dropped from 104 millibars, to 87 millibars, and finally to 71 millibars, before they were rescued by Voyager. (VOY: "Day of Honor")
