Pressure

Pressure (𝑝 :Nm−2=Pa) is a measure of the force applied perpendicular to a two-dimensional, surface, e.g. the force per square meter applied to the container of a gas.

𝑝=𝐹𝐴

or, with vectors

⃗𝐅=𝑝⃗𝐀

Like Temperature, the pressure of a gas is only a measurable/meaningful quantity when the gas is in Thermal equilibrium.
