Difference Between Stress and Pressure

 7 Differences Between Stress and Pressure

S.NO.	Stress	Pressure
1.	Stress is a measure of the internal forces acting within a body.	Pressure is a measure of the force per unit area acting on a surface.
2.	Stress is a measure of the force per unit area within a body.	Pressure is a measure of the force per unit area acting on a surface.
3.	Stress is a measure of the internal forces within a body that can cause it to deform or change shape.	Pressure is a measure of the force acting on a surface that can cause it to deform or change shape.
4.	Stress is typically measured in units of force per unit area, such as pascals (Pa).	Pressure is also typically measured in units of force per unit area, such as pascals (Pa).
5.	Stress is a scalar quantity, meaning it has only magnitude.	Pressure is also a scalar quantity.
6.	Stress is a measure of the internal forces acting within a body.	Pressure is a measure of the external forces acting on a body.
7.	Stress can be caused by external forces acting on a body, such as gravity or mechanical loads.	Pressure is always caused by external forces acting on a surface.
