Pascal's principle: Pascalâs principle, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.
Pascal (Pa) 1 pascal = a force of 1 Newton per square meter. 1 Newton is the force required to accelerate 1 kilogram one meter per second per second = 1 kg Â· m/s 2; this is actually quite logical for physicists and engineers. 1 pascal = 10 dyne/cm 2 = 0.01 mbar. 1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi.
