UNIT CONVERTER

Stress and modulus

For tensile, compressive and shear stress and elastic modulus; separate from fluid pressure.

Result

SI / metric also includes non-SI metric units. Check distinctions such as US and UK units.

About stress and modulus conversion

Choose the input and output units, then enter a number. The result updates on this device.

Conversion examples (rounded)

  • 1 MPa = 1 N/mm²
  • 10 MPa = 10 N/mm²

Some supported units: Pa · kPa · MPa · GPa · N/m² · N/mm² (11 units in this category).

For tensile, compressive and shear stress and elastic modulus; separate from fluid pressure.

The nearby list shows the reference unit and up to two rows on either side. Expand it to see every unit. Check SI / metric, imperial / US customary and other definitions before important use.

Are MPa and N/mm² the same?

1 MPa equals 1 N/mm². A pascal is N/m²; the area conversion changes the factor.

  • 1 MPa = 1 N/mm²
  • 1 kgf/mm² = 9.80665 MPa
Is kg/mm² the same as kgf/mm²?

kg is a unit of mass; kgf is a unit of force. Check what the notation means in your material data. This page converts stress and modulus units; it does not determine allowable stress or a safety factor.
