Using the pressure units
Here's a list of some common pressure units and where they're used:

Pa: Also known as Pascal, it is commonly used in scientific and engineering research, vital for precise pressure measurements in material and industrial sciences.

Psi: Pounds per square inch is commonly used in measuring tire or tube pressure in vehicles.

Bar: Primarily used in meteorology to read atmospheric pressure, but can also be used for tire pressure measurements in vehicles.

Atm: Atmosphere is a standard unit of measurement for atmospheric pressure, everyday weather predictions, and understanding altituderelated effects on the environment, such as when cooking or baking at high elevations.
Using the pressure unit converter
Our pressure unit converter can help you measure and transform your pressure values as follows:
 In the calculator, choose your desired pressure unit, e.g., bar.
 Then simply enter your pressure value, e.g., 50 bars.
 And the calculator will provide you with the pressure values in different units, i.e.,

Pressure in bar
50 bar 
Pressure in pounds per square inch
725.189 psi 
Pressure in atmospheres
49.3462 atm 
Pressure in pascals
5,000,000 Pa.
You can also select more pressure units like Torr, kPa, and pounds per square foot from the dropdown menu to convert between pressure units in realtime with precision.

Convert between pressure units
Let's talk about the fundamental formulas and conversion factors that we can use to convert between different pressure units.

Pascals Pa to Kilopascals kPa:
kPa = Pa / 1000

Torr to Millimeters of Mercury mmHg:
mmHg = Torr

Barometric Pressure bar to Pounds per Square Inch psi:
psi = bar × 14.5038

Atmospheres atm to Pascals Pa:
Pa = atm × 101325
