Calculate normal or shear stress from force and area (σ = F/A), or stress from strain with Young's modulus (σ = Eε), in MPa, GPa, psi, or ksi.

σ = F / A
Force perpendicular to the cross-section, tension or compression. The same formula gives average shear stress τ = F / A for a force parallel to the section.

Working
Choose axial stress (σ = F/A) or Hooke's law (σ = Eε) and which quantity to solve for; the form asks only for the others.
Each input has its own unit picker (kΩ, µF, mH, MPa, GPa, mm, cP and more), so there's nothing to convert first.
You get the result in your chosen unit and every other unit, plus the rearranged equation with your numbers in SI units.
Pascals (N/m²). Engineering stresses are usually in MPa, which equals N/mm², or in psi and ksi in US units.
Normal stress comes from a force perpendicular to the cross-section (tension or compression); shear stress from a force parallel to it. Both average out to force divided by area.
Only while the material behaves elastically, below its yield or proportional limit. Mild steel yields at around 250 MPa.
