Is it correct to use the unit Pascal (Pa) for both fluid pressure and Stress in solids? Reference would be ok?

Question

Please give me a reference that can verify you answer.

Answer 1

Pressure and stress both denote force acting upon unit area.

Pascal is N/sq.mtr, where Newton is a unit for force and sq.mtr is a unit for unit area. So, technically you can use it but in general we speak stress interms of N/sq.mtr (or any other area units)

Answer 2

Yes, the unit of these both quantities is Newton per square meter and their dimension and also physical behavior are the same, so we can use unit Pascal for both of them which is defined as N/m^2.

Answer 3

Pascal is for atmospheric pressure.
Newton per meter square is for stress

Answer 4

fluid pressure is measured in pascals(newton/metre^2)
however stress is usually expressed in megapascal(newton/mm^2)--according to the metric system
