mmHg to Pa (pascals) Conversion Table

The following calculation explain how to derive the conversion factor for converting millimeters of mercury column to pascals:

  • 1 Pa = 1 pascals (Pa)
  • 1 mmHg = 133.322 pascals (Pa)
  • pascal value x 1 Pa = mmHg value x 133.322 Pa
  • Pa value =  mmHg value x 133.322
