mmHg is a unit of measurement that determines an object's pressure using the manometric unit.
Additionally, it can be thought of as the additional pressure created by a mercury column that is one millimetre high. Additionally, it is currently specified as 133.3223 Pascals precisely.Approximately 1 Torr, or 1 / 760 of the ordinary atmospheric pressure (101325 / 760 = 133.322368421053 Pascals), is equal to one millimetre of mercury.the dimension of force per unit area is ML-2T-1 its actually of a pressure. its a relationship between mass, length and time.In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area.
