numerical values โ€‹โ€‹of pressure, given in millimeters of mercury column , for expression in Pascal multiply by 101325 and divide by 760, since, according to tabulated data of 1 mm Hg.Art.101325/760 = Pa.The formula for the transfer of units is as follows: Pp = Pm * 101325/760, gdePm - pressure expressed in millimeters of mercury column , Pp - pressure expressed in Pascal.

not always necessary to use a precise formula set forth in the first paragraph.In practice, use a simple formula: Pp = 133.322 * Pm or Pp = Pm * 133 in cases where the accuracy of the results should be in the sign of units.

In Russia, the standard unit is the millimeter of mercury column .Often, however, when re
porting the results of the measurements lowered names of units up to the fact that blood pressure is expressed only numerically, for example, 120 to 80. This can be seen in the meteorological reports and engineers in the production process vacuum systems.The physical vacuum has a very low pressure, which is measured in microns for the convenience of the mercury column .Microns to one thousand times less than a millimeter.In all cases, if you can not update the data, use the above formula for the transfer of pressure mmHg post in Pascali .

for high pressure unit is traditionally used called "atmosphere", which is equivalent to the normal atmospheric pressure.In numerical terms, 1 atm = 760 mm Hg.Art.From this relation by simple conclusions can be obtained from the dependence of the atmospheres Pascal Pa Pp = 101325 * where Pa - pressure expressed in atmospheres.For practical calculations using the formula: Pp = Pa * 10000.

If the pressure is given in the technical atmosphere, then transfer to post mmHg its value must be multiplied by 735.56.
