Symbol Meaning SI unit of measure magnetic vector potential: tesla meter (T⋅m) : area: square meter (m 2) : amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2)
The symbol for it is "p" or P. [2] The IUPAC recommendation for pressure is a lower-case p. [3] 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 style.
(lowercase) represents: a plane angle in geometry; the angle to the x axis in the xy-plane in spherical or cylindrical coordinates (mathematics) the angle to the z axis in spherical coordinates (physics) the potential temperature in thermodynamics; theta functions; the angle of a scattered photon during a Compton scattering interaction

p →: Product of an object's mass and velocity kg⋅m/s L M T −1: vector, extensive Pop: p →: Rate of change of crackle per unit time: the sixth time derivative of position m/s 6: L T −6: vector Pressure gradient: Pressure per unit distance pascal/m L −2 M 1 T −2: vector Temperature gradient
Psi / ˈ (p) s aɪ, ˈ (p) s iː / (P)SY, (P)SEE [1] (uppercase Ψ, lowercase ψ or 𝛙; Greek: ψι psi) is the twenty-third and penultimate letter of the Greek alphabet and is associated with a numeric value of 700. In both Classical and Modern Greek, the letter indicates the combination /ps/ (as in English word "lapse").
Says the article "The upper case P is normally reserved for power." well (as noted above), the lower case p is normally reserved for momentum (sure it's a vector but often written as a scalar). In chemistry & physics it's P. If it's a dicipline-related thing then the "p sometimes P" bit currently on the page is rubbish.
a probability (as in P(E), which reads "the probability P of event E happening") p represents a prime number; the numerator of a fraction; the unit prefix pico (10 −12) [10] a proton, often p + or 1 1 p; the linear momentum in physics equations [10] the perimeter of a triangle or other polygon; generalized momentum [10] the pressure in ...
