symbol	psi, lbf/in²

The pound per square inch (psi, lbf/in²) or psi is a unit of pressure.

The "pound" in "pound per square inch" is the pound-force, not to be confused with the pound the unit of mass. One pound-force is the force exerted downward by a mass of one avoirdupoids pound on the surface of the Earth.

Definition of the pound per square inch

One psi is equal to the pressure exerted by a force of one pound-force on a surface of one square inch.

Equivalences

One psi is equivalent to:

Some Facts

Pressures in the megapascal range can be found at 100 meters under the sea, at the nozzle of a pressure washer or under a woman's foot. Indeed, considering a woman of 50 kg and a heel radius of 6 mm, every step she would pummel the ground with 4.3 megapascals of pressure, far more than what an elephant can create on one foot. One point for the ladies, I guess.

Prefix

mega

10⁶

The prefix mega- comes from the ancient Greek mégas meaning great. The associated multiplicative factor is 1 000 000 or 10⁶.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
