Pressure Unit Conversion Calculator

How to use the Pressure Unit Conversion Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

bar = psi

bar = atm

bar = pascal

Frequently asked questions

What are the common units of pressure?

The common units of pressure include Pascals (Pa), atmospheres (atm), millimeters of mercury (mmHg), bar, and pounds per square inch (psi). Each unit represents pressure but may be used in different contexts, such as scientific calculations, meteorological data, and engineering applications.

How do I convert between different pressure units?

Converting between pressure units involves using conversion factors. For example, to convert psi to atm, you can multiply the psi value by 0.068046. Using an online pressure unit conversion calculator can simplify this process, ensuring accuracy and efficiency.

What is the difference between absolute and gauge pressure?

Absolute pressure measures pressure relative to a perfect vacuum, while gauge pressure measures pressure relative to atmospheric pressure. Therefore, gauge pressure can sometimes show a value of zero when the pressure equals atmospheric pressure, while absolute pressure will never be zero under normal conditions.
