Pressure Converter

How does the pressure converter work?

The pressure converter is used to convert different units of measurement for pressure. Select the original unit or "from unit" (examples: Pascal Pa, pounds per square inch PSI, Bar, and more). Next, enter the numeric "value" of pressure, then select the unit of measurement you would like the outcome to be "to unit" and click the "convert" button.

Why use the pressure converter

The pressure converter is a useful tool that can be applied for numerous cases, for example when traveling to and from different regions of the world where one may still be using the imperial system of measurements and another using the metric system! Often used when in the garage, pressure conversions are necessary to ensure properly functioning systems on your vehicle!

A Brief History of the Metric System

The metric system was practically realized during the French Revolution around 1799, after the existing system became too impractical for proper trade, it was then replaced by a decimal system based on the kilogram and the meter which are units of measurement inspired by nature itself. To ensure the precision of the metric units, scientists have created objects that define what the units are exactly, for example, a round ball often referred to as the world's roundest object was made to reference exactly what a kilogram is and scales are calibrated based on this object specifically. The other units such as grams are filled in using their respective mathematical relationship to the kilogram.

Input fields explained

Before using the pressure converter, it may help to understand each input field.

• From unit:

  Select the unit of measurement you are using and would like converted.

• Value:

  Enter the numeric value of your measurement.

• To unit:

  Choose the unit of measurement you wish to be converted into.

Understanding the results

Below is a helpful example and demonstration of how the pressure converter functions.

Example: you have a pressure reading of 5,000 Pa and need it converted to PSI, select Pascal (Pa) in the "from unit" input field, enter 5,000 in the "value" field then choose PSI in the "To unit" field, and finally click the "convert" button!

To go from Pascal (Pa) to pound per square inch (Psi), divide the pressure value by 6895

        5,000 Pa / 6895
        = 0.725 Psi
        

To go from pound per square inch to Pascal, multiply the pressure value by 6895

        5 Psi X 6895
        = 34,473.8 Pa
        

To go from Bar to a pound per square inch, multiply the pressure value by 14.5

        2 Bar X 14.5
        = 29 Psi
        

To go from Pound per square inch to bar, divide the pressure value by 14.5

        25 Psi / 14.5
        = 1.7 Bar
