The Pound Per Square Foot (psf) in Pressure

What is Pound Per Square Foot (psf)

Pound per square foot (psf) is a unit of pressure measurement that expresses the force applied over a certain area. Specifically, it refers to the pressure exerted by a force of one pound acting on an area of one square foot. This unit is commonly used in various fields, including engineering, construction, and meteorology, to quantify pressure in various applications.

Mathematically, pressure can be defined as:

Where:

• P is the pressure,
• F is the force applied,
• A is the area over which the force is distributed.

In the case of psf, the force is measured in pounds and the area in square feet.
