WebThe standard atmospheric pressure is 1013.25 mbar, which is equivalent to 29.92 inHg or 14.696 psi. Another unit of measure sometimes used for blood pressure is the pascal (Pa), which is the SI unit of pressure. One pascal is equal to one newton per square meter, and one atmosphere is equal to about 101,325 Pa. WebThis type of pressure measurement is commonly used to measure the pressure drop in a fluid system. Since a differential pressure is a measure of one pressure referenced to another, it is not necessary to specify a pressure reference. For the English system of units this could simply be psi and for the SI system it could be kPa. In addition to ...
