psi to MPa converter
1 psi = 0.00689476 MPa
And 1 MPa = 145.038 psi. Pounds per square inch to megapascal.
Formula
MPa = psi × 0.00689476
A reading of 15 psi is 15 × 0.00689476 = 0.103421 MPa.

About these units
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
MPa (megapascal): Standard for material strength, hydraulics and pressure vessels; equal to 1 N/mm².
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
