Pressure Converter

Pressure Converter is a tool that automatically converts one pressure unit (which you enter below) to another pressure unit. You can quickly convert psi to bar, MPa to bar, or kPa to bar. If you have different units on your compressor than on your tire, using this converter can be very helpful.

For example, if you want to convert Pascals to mmH2O, enter the Pascal value in the first field and read the result in the Millimeters of Water Column field. The results are displayed to six decimal places.

About Pressure Unit Converter

The Pressure Unit Converter converts one unit of pressure into another.

In everyday life, you will often come across devices or objects that display pressure values in different units. Examples include car tires, bicycle tires, compressors, bicycle pumps, and scuba tanks. If you have a device that displays different pressure units than, say, a tire, it's a good idea to use this tool to convert them and make sure the tire has the correct pressure.

In the converter available on this page, it is possible to convert the pressure in the middle of the following units:

It takes a while to convert psi to bar, kPa to bar, or MPa to bar.

What is pressure?

Pressure is a physical quantity that describes the force applied to a unit area. It can be defined as the force perpendicular to a surface divided by its area. It is expressed in units of force per unit area, such as pascals (Pa) in the SI system.

Pressure can be exerted by various agents, such as gases, liquids, or solids. Gases and liquids exert pressure on the surrounding walls of a vessel or surface by the chaotic motion and interaction of molecules. These forces cause the particles to hit the walls of the vessel, resulting in a force on the surface.

In the case of gases, pressure depends on the number of molecules, their velocity, and the volume they occupy. The greater the number of gas molecules, the greater the speed of their movement, and the smaller the volume, the greater the pressure.

In everyday life, we encounter various units of pressure, such as atmosphere (atm), bar (bar), or millimeters of mercury (mmHg). These units are used to measure atmospheric pressure, tire pressure, or blood pressure in the human body.

Pressure plays an important role in many fields, including physics, chemistry, meteorology, engineering, and medicine. It is the basis for the operation of many devices such as pumps, motors, compressors, and is also important for maintaining thermal and mechanical balance in living organisms.
