mmHg to inHg Conversion Table

The conversion calculation from millimetres of mercury to inches of mercury over the vacuum and atmospheric pressure range is as follows:

• 1 inHg = 3386.39 pascals (Pa)
• 1 mmHg = 133.322 pascals (Pa)
• inHg value x 3386.39 Pa = mmHg value x 133.322 Pa
• inHg value = mmHg value x 0.0393701

Alternatively a simpler and more obvious calculation can be used from the known conversion factor for a length measured in millimetres converted to inches:

• 1 mm = 0.0393701 in
• mmHg value = inHg value x 0.0393701
