mbar to kPa converter
1 mbar = 0.1 kPa
And 1 kPa = 10 mbar. Millibar to kilopascal.
Formula
kPa = mbar × 0.1
A reading of 15 mbar is 15 × 0.1 = 1.5 kPa.

About these units
mbar (millibar): Used for weather, vacuum and low differential pressures.
kPa (kilopascal): Common for HVAC, building ventilation and low-pressure gas work.
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.
