Millimeters of mercury to megapascal Conversion
1 millimeters of mercury (mmHg) is equal to 0.0001333223874 megapascal (MPa).
1 mmHg = 0.0001333223874 MPa
or
1 MPa = 7500.615758 mmHg
Formula
To convert a pressure from millimeters of mercury (mmHg) to megapascal (MPa), divide the pressure in millimeters of mercury by 7500.615758
p(MPa) = p(mmHg) / 7500.615758
Examples:
Convert 5 millimeters of mercury to megapascal:
p(MPa) = 5mmHg / 7500.615758 = 0.0006666119371 MPa
