Atmospheres and Pascals are two important units of pressureThis example problem demonstrates how to convert the pressure units atmospheres atm to pascals Pa. So 5 Pa below atmospheric pressure -5 Pa gauge would be a very slight suction pressure but if it is 5 Pa above a perfect vacuum 5 Pa absolute it would be a strong vacuum at the opposite.
