Formula and method

psi = MPa × 145.03773773 MPa = psi × 0.006894757 Multiply by the source unit’s SI factor to get Pa, then divide by the target unit’s SI factor.

Worked example

10 MPa × 145.03773773 = 1,450.377377 psi.

Assumptions and limits

1 MPa = 10 bar = 1 N/mm² exactly; the chart includes common PN and hydraulic pressure steps.
Results show up to 6 decimals; Copy and CSV keep more digits.

Frequently asked questions

How many psi are in 1 MPa?

1 MPa = 145.03773773 psi. The factor follows from the SI definitions: 1 psi = 1 lbf/in² = 4.4482216152605 N ÷ (0.0254 m)²; 1 bar = 100,000 Pa.

How do I convert psi back to MPa?

Multiply by 0.006894757 (or divide by 145.03773773), or simply switch “From unit” to psi. For example 10 psi = 0.068948 MPa.

How do MPa and ksi relate for material strength?

1 ksi = 1,000 psi ≈ 6.894757 MPa and 1 MPa ≈ 0.145038 ksi. Metric datasheets give yield and tensile strength in MPa (equal to N/mm²), US ones in ksi; divide the psi result here by 1,000 to get ksi.
