mbar to psi converter
1 mbar = 0.0145038 psi
And 1 psi = 68.9476 mbar. Millibar to pounds per square inch.
Formula
psi = mbar × 0.0145038
A reading of 15 mbar is 15 × 0.0145038 = 0.217557 psi.

About these units
mbar (millibar): Used for weather, vacuum and low differential pressures.
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
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.
