Modulus of elasticity = Stress\Strain --> Force upon area/Change in length upon length = Force upon area.

Stress = Force upon area.

Strain = Change in length upon length.

Pressure = Force upon area 0.

Modulus of rigidity = Shear stress upon shear strain = Force upon area.

Stress unit = pressure unit = modulus of rigidity = N/MM^2.
