About these units
Pascal (Pa). The pascal is the SI unit of pressure, one newton per square meter. Because it is small, practical values are often quoted in kilopascals, bar or atmospheres.
Millimeter of Mercury (mmHg). A millimeter of mercury is the pressure exerted by a one-millimeter column of mercury, about 133.32 pascals. Blood pressure and vacuum measurements are still quoted in mmHg.
