Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. ... Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as 1⁄760 of this.

Answer:
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as 1⁄760 of this.
SI unit: Pascal
In SI base units: 1 N/m2, 1 kg/(m·s2), or 1 J/m3
Derivations from other quantities: p = F / A
