Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure.

Pressure measurement is the measurement of an applied force per unit area by a fluid on a surface. Pressure is typically expressed in units of pascals in the International System of Units. Many techni
Pressure
…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. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these derive from a…
