WebSI base units The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, as given in Table 1. For detailed information on the SI base … Pressure is the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used. The usage of P vs p depends upon the field in which one is working, on the nearby presence of other symbols for quantities such as power and momentum, and on writing st…
