1.7 Pressure and density The standard unit of pressure in the SI system is the pascal (Pa), where 1 Pa = 1 N/m2. Static pressure (P0) The static pressure at a point in the medium is the pressure that would exist at that point with no sound waves present. At normal barometric press...
The many equivalent units at present used, and their interrelation, are discussed more fully inCh.10.7with special reference to steam pressures, where it is suggested that the SI unit based on the pascal (or newton per metre2) is the most logical, consistent and ultimately the most convenient...

The units were able to accurately measure pressures as low as 40 billionths of a pascal (Pa), the SI unit of pressure, within 2.6 percent. That’s about the same as the pressure surrounding the International Space Station. Atmospheric pressure at sea level is around 100,000 Pa. ...
