Pascal
A pascal (or Pa) was a unit of pressure equal to 1/100 millibar.

The warp core pressure aboard  starship was measured in both kilopascals or megapascals. ()

Comparative list of pressure
Kilopascal = 1 thousand pascals
2 kilopascals: The internal pressure aboard a Borg cube was two kilopascals above what was normal on a Federation starship. ()

90 kilopascals: The pressure encountered from the leading edge of shock waves encountered by the USS Voyager following the explosion of a supernova was over 90 kilopascals – over 30% higher than predicted. ()

102.875 kilopascals: The pressure on a structure inside the Bajoran wormhole encountered by Benjamin Sisko and Jadzia Dax in 2369 was 102.875 kilopascals. ()

2,100 to 2,500 kilopascals: Upon being pulled into the Delta Quadrant, the 's warp core pressure was down to 2,100 kilopascals. Upon unlocking the magnetic interlocks, they were able to increase it to a stable rate of 2,500 kilopascals. ()

Megapascal = 1 million pascals
 36 to 53 megapascals: When Voyagers matter-antimatter reactor was at eighty percent of critical, Harry Kim observed that the warp core pressure was at 36 megapascals and rising. B'Elanna Torres then instructed that when the pressure reached 53 megapascals, she would trigger the shock pulse, adding that they should get out of engineering by the time the pressure reached 50 megapascals. As the pressure continued to rise, a microfracture formed in the dilithium matrix at 41 megapascals, which was sealed by the time the pressure reached 44 megapascals. By this point the ship was shaking rather violently, indicating to the crew elsewhere that the warp core was heating up and a breach was imminent. From that point, the pressure rose quickly, "47, 48, 49", as engineering was ordered to be evacuated and the crew took cover. ()
