Young Modulus Calculator
Work out young modulus instantly with clear inputs, formula shown and shareable results.
About Young Modulus Calculator
Young's modulus is the slope of the elastic part of the stress-strain curve, stress divided by strain. 150 MPa producing 714 microstrain gives 210 GPa, the standard figure for steel. Because modulus is a material property, it is unaffected by the specimen's size - unlike stiffness, which also depends on geometry.
Formulas
Young's modulus
E = stress / strain
Typical values
steel 200-210 GPa, aluminium 69 GPa, concrete 30 GPa

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
Is a stiff material also strong?
Not necessarily. Modulus measures resistance to elastic deformation; strength is the stress at which it fails. Glass is stiff but brittle.
Does heat treatment change the modulus?
Barely. Modulus depends on atomic bonding, so hardening changes strength dramatically while leaving stiffness almost untouched.
