mbar = mmHg × 1.33322387415

Definitions: 1 mbar = 0.001 bar; 1 mmHg = 133.322387415 Pa

The millibar (mbar) is one thousandth of a bar and equals exactly one hectopascal. It is the traditional unit for atmospheric pressure in meteorology and aviation, and it is common for vacuum pressures.

The millimeter of mercury (mmHg) is the pressure at the base of a one-millimeter column of mercury. It is the unit of blood pressure in medicine, for example 120/80 mmHg, and is also used for some barometric and vacuum readings.
