Final answer:
The unit of pressure that is not listed is mm.
Step-by-step explanation:
The unit of pressure that is not listed is D. mm.
Pressure can be measured using several different units, including pounds per square inch (psi), pascals (Pa), millimeters of mercury (mm Hg), millibars (mb), and atmospheres (atm). However, mm is not a standard unit of pressure.
Examples of common pressure units:
- psi - used in some applications such as measuring tire pressure
- Pa - the standard SI unit of pressure
- mm Hg - also known as torr, commonly used in blood pressure measurements
- mb - used in meteorology to measure atmospheric pressure
- atm - commonly used to measure atmospheric pressure at sea level
