Pressure Converter

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.

• 1 atm = 1.01325 bar → atm to bar
• 1 atm = 101.325 kPa → atm to kPa
• 1 atm = 101325 pascals → atm to pascal
• 1 atm = 0.101325 MPa → atm to MPa
• 1 atm = 14.6959 psi → atm to psi
• 1 atm = 760 torr (mmHg) → atm to torr

Bar Conversion:

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

• 1 bar = 0.986923 atm → bar to atm
• 1 bar = 29.529983071 inHg → bar to inHg
• 1 bar = 1.019716213 kg/cm² → bar to kg/cm²
• 1 bar = 100 kPa → bar to kPa
• 1 bar = 1000 millibars → bar to millibar
• 1 bar = 100000 pascals → bar to pascal
• 1 bar = 0.1 MPa → bar to MPa
• 1 bar = 14.5038 psi → bar to psi
• 1 bar = 750.062 torr (mmHg) → bar to torr

Inch of Mercury Conversion:

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

• 1 inHg = 3.3863886667 kPa → inHg to kPa
• 1 inHg = 33.863886667 millibars → inHg to millibars

Kilopascal (kPa) Conversion:

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

• 1 kPa = 0.00986923 atm → kPa to atm
• 1 kPa = 0.01 bar → kPa to bar
• 1 kPa = 0.01019716213 kg/cm² → kPa to kg/cm²
• 1 kPa = 0.001 MPa → kPa to MPa
• 1 kPa = 1000 pascals → kPa to pascal
• 1 kPa = 0.145038 psi → kPa to psi
• 1 kPa = 7.50062 torr (mmHg) → kPa to torr

Pascal Conversion:

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

• 1 pascal = 0.000009869 atm → pascal to atm
• 1 pascal = 0.00001 bar → pascal to bar
• 1 pascal = 0.01 kPa → pascal to kPa
