Pressure Pounds per Square Inch: A Comprehensive Guide

Pressure pounds per square inch (psi) is a unit of measurement that quantifies the force applied perpendicularly to a surface per unit area. It is a fundamental quantity in fluid mechanics, engineering, and atmospheric sciences.

Conversion and Equivalents

1 psi is defined as the force of one pound-force (lbf) distributed over an area of one square inch (in²). It can be converted to other pressure units using the following equivalencies:

Applications

Pressure pounds per square inch has numerous applications across various industries and fields:

• Fluid Power: Psi is the standard unit of measurement for hydraulic and pneumatic systems, which use pressurized fluids or gases to transmit power.
• Engineering: Engineers use psi to calculate stresses and loads on structures, pipelines, and components.
• Atmospheric Sciences: Meteorologists measure atmospheric pressure in psi to predict weather patterns and study climate change.
• Medical: Blood pressure, which measures the force exerted by blood against the walls of arteries, is typically expressed in psi.
