1 Pascal = 0.00000986923267 Atm
Pascal is a metric pressure unit and defined as a force of newton per square meter. It can be formulated as : 1 Pascal = Newton / m2 or 1 Pascal = Kilogram / meter * second2. The abbreviation is "Pa".
Atm (or atmospheric pressure) is defined as the force per unit area by the weight of air above that point. 1 atmosphere is about 101.325 kilopascals.
