Microns of mercury to Barg (gauge bar) Converter

Convert microns of mercury (µmHg) to barg (gauge bar) (barg) with the formula and table below.

Quick answer

  • Formula: barg = µmHg × 0.000001333224 − 1.01325
  • Example: 1 µmHg = -1.0132487 barg

1 micron of mercury = -1.013248667 barg (gauge bar)

How to convert microns of mercury to barg (gauge bar)

barg = µmHg × 0.000001333224 − 1.01325

This conversion is not a simple multiplication, so the size of one unit alone does not tell you the answer. Example: 1 µmHg = -1.013248667 barg. For the reverse, see barg (gauge bar) to microns of mercury.
