Pressure Converter

Pressure converter to convert all pressure units. Input a value in the provided field and choose the pressure units you wish to convert between.


The pressure unit converter provides quick and accurate conversions, making it a valuable tool for engineers, scientists, meteorologists and anyone dealing with pressure measurements.

Here's a step-by-step guide on how to use the pressure converter:

1. Enter the value you want to convert.

2. Select the desired accuracy level from the provided drop-down list. By default, the converter is set to round the results to 12 decimal places.

3. Select the initial pressure unit you wish to convert from.

4. Select the target pressure unit you wish to convert to.

5. Click on the "Convert" button.

6. The converter will instantly displays the converted pressure value, rounded to four decimal places by default.

Popular Pressure Units:

1. Pascal (Pa): The SI unit of pressure, commonly used in scientific and engineering applications.

2. Bar (bar): Widely used in meteorology, industrial processes, and fluid dynamics.

3. Pound per Square Inch (psi): Commonly used in the United States for measuring pressure in various industries.

4. Atmosphere (atm): A unit used to express atmospheric pressure, especially in weather reports.

5. Millimeter of Mercury (mmHg): Often used in medical settings for blood pressure measurements.

Metric vs Imperial Pressure Units:

In the Metric system, the Pascal (Pa) is the primary unit for pressure. However, the Bar (bar) is also commonly used for expressing pressure in Metric applications.

In the Imperial system, the most popular pressure unit is the Pound per Square Inch (psi). However, other units like inches of mercury (inHg) and pounds per square foot (psf) are also used in specialized fields.

The most frequently converted pressure units:

The most frequently used units of pressure are pascal (Pa), kilopascal (kPa), megapascal (MPa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar.

Atm (Atmospheric Pressure) Conversion:

An atmosphere (atm) equals to the air pressure at the sea level at a temperature of 15 Celsius.

Bar Conversion:

Bar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure.

Inch of Mercury Conversion:

Inch of Mercury (inHg) is the pressure exerted by a column of mercury 1 inch (25.4 mm) in height.

Kilopascal (kPa) Conversion:

Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre).

Pascal Conversion:

Pascal is the unit of pressure in the metric system and is equal to 1 newton per square meter.

Psi (Pound Force Per Square Inch) Conversion:

Psi is a pressure unit and equals to the force of one pound applied to one square inch.
