Explanation:
Detailed explanation-1: -A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals or exactly 133.322 pascals. It is denoted mmHg or mm Hg.
Detailed explanation-2: -Because the boiling point of mercury is quite high (356.73°C), there is very little mercury vapor in the space above the mercury column. Thus a pressure of 1 atm equals 760 mmHg exactly and is approximately equal to 100 kPa.
Detailed explanation-3: -Pressure is measured in millimetres (mm) of mercury (Hg). A special unit that measures pressure shows how high a column of mercury rises.
