Pascal
Description
The pascal [Pa] is the SI unit for pressure. [Pa] = [J·m-3] = [N·m-2] = [m-1·kg·s-2].
The standard pressure is 100 kPa = 1 bar (105 Pa; 1 kPa = 1000 Pa). Prior to 1982 the standard pressure has been defined as 101.325 kPa or 1 standard atmosphere (1 atm = 760 mmHg).
Abbreviation: Pa
