Millimeters of mercury to inch of mercury Conversion

1 millimeters of mercury (mmHg) is equal to 0.03937007874 inch of mercury (inHg).

1 mmHg = 0.03937007874 inHg

1 inHg = 25.4 mmHg

Formula

To convert a pressure from millimeters of mercury (mmHg) to inch of mercury (inHg), divide the pressure in millimeters of mercury by 25.4

p_(inHg) = p_(mmHg) / 25.4

Examples:

Convert 100 millimeters of mercury to inch of mercury:

p_(inHg) = 100mmHg / 25.4 = 3.937007874 inHg
