mbar to bar converter
1 mbar = 0.001 bar
And 1 bar = 1,000 mbar. Millibar to bar.
Formula
bar = mbar × 0.001
A reading of 15 mbar is 15 × 0.001 = 0.015 bar.

About these units
mbar (millibar): Used for weather, vacuum and low differential pressures.
bar (bar): Close to one atmosphere; widely used for industrial and pneumatic gauges outside the US.
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.
