Convert millipascals to psi

Explanation

From this page you can convert millipascals to pounds per square inch (or mPa to psi) simply, by using the application above.

In case you are wondering, to convert from millipascals to pounds per square inch you need to multiply by 0.000000145. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 mPa≈0.000000145 psi

The millipascal (mPa) is a unit of pressure.

Definition of the millipascal

One millipascal is equal to 0.001 pascals.

Equivalences

Here are some equivalences between the millipascal and other pressure units:

Some Facts

A pressure in the order of the millipascal is pretty insignificant. A sheet of paper laying flat on a table somewhere on Earth would apply a pressure of roughly 600 millipascals by itself. The pressure created by the atmosphere above the sheet of paper would be tens of thousands of time greater.

Prefix

milli

10^-3

The prefix milli- comes from the Latin mille meaning a thousand. The associated multiplicative factor is 0.001 or 10^-3.

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.

pounds per square inchpsi

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:
