inHg to mbar Conversion Table

The conversion formula to convert inch of mercury (inHg) into millibar (mbar) over the atmospheric pressure range can be calculated as follows:

  • 1 mbar = 100 pascals (Pa)
  • 1 inHg = 3386.39 pascals (Pa)
  • mbar value x 100 Pa = inHg value x 3386.39 Pa
  • mbar value = inHg value x 33.8639
