Convert one psi to kilopascals

Explanation

To convert one pound per square inch to kilopascals all we need is to know the conversion factor and we are done. Luckily, we can compute that factor using the units' definitions below.

We find that one pound per square inch is approximately equal to 6.8948 kilopascals.

Formula

1 psi ≈ 6.8948 kPa

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.

Some Facts

The pressure inside a bottle of champagne is between 400 and 600 kilopascals. It is enough to propel the cork at more than 12 m/s or 27 mph. So be careful.

Prefix

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.
