Convert stress units including pascals, kilopascals, megapascals, gigapascals, psi, ksi, pounds per square foot, kilograms-force per square centimeter, and more.
Megapascals to psi:
1 MPa = 145.038 psi
PSI to megapascals:
1 psi = 0.00689476 MPa
KSI to megapascals:
1 ksi = 6.89476 MPa
Gigapascals to ksi:
1 GPa = 145.038 ksi
Stress conversions are useful for steel yield strength, concrete strength, wood design values, bolts, welds, beams, columns, pressure vessels, mechanical parts, material testing, and engineering specifications.
Use this converter when comparing SI, U.S. customary, and material strength stress units.
Your result shows the entered stress converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and material design, make sure the stress unit matches your drawing, design code, material data sheet, test report, or structural calculation.
Stress is force divided by area. It describes the internal force intensity within a material or member.
The SI unit of stress is the pascal, abbreviated as Pa. In engineering, MPa and GPa are also very common.
Stress and pressure use the same units, but stress is usually used for forces inside materials while pressure is usually used for fluids or loads over surfaces.
One megapascal equals approximately 145.038 psi.
This converter is designed for stress magnitude conversions, so it uses non-negative values.
