Pressure Converter

This pressure converter features 31 pressure units. This makes it possible to convert between American, British, metric, and other pressure units as desired. All values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.

Two Steps to Your Result

Our pressure converter offers several input fields, each displaying the current unit symbol (for example, bar, psi or mmHg). To change a unit, simply click on the unit symbol and select your preferred measurement from the dropdown menu.

Once you have selected the desired units in the pressure converter, simply enter the value you want to convert. You can input numbers into any of the available fields. As soon as you enter a value in one field, all other fields will automatically update and display the converted results. Both the entered value and the calculated results are automatically rounded to the predefined number of decimal places.

At the bottom of the pressure converter, you will find two green buttons. The button on the right resets the converter to its default state. This restores all units, values, and decimal settings to their original configuration. The button on the left clears the current inputs by setting all values to zero, while keeping your selected units and decimal settings unchanged.

Conversion table for pressure units

Pressures are always specified with a value and the corresponding unit. A conversion table allows the value of a known pressure unit to be converted into another unit. Example conversion: How many bar are in 1 psi?. In most cases, a conversion table is used to determine the appropriate conversion value or calculation method for converting one unit of pressure into another. Due to their complexity, these tables are often confusing, making them difficult for beginners to understand.

The following tool offers a solution to this problem, allowing conversion values and calculation methods to be retrieved directly from the conversion table. The conversion table covers a total of 31 different units of measurement.

Converting pressures in everyday life

There are many pressure units that are rarely used in everyday life. These include, for example, the technical atmosphere [at] or decapascal [daPa]. It is also unlikely that very low pressures will be converted to gigapascals [GPa]. For this reason, it is not necessary to know all conversion values by heart. However, there are pressure units that are used very frequently in everyday life. Examples include bar [bar], pascal [pa] and pounds per square inch [psi]. For these units, it can be very helpful to know the calculation method and the conversion value by heart.

Converting bar and psi

The tire pressure for bicycles, motorcycles and cars is often specified in pounds per square inch [psi] instead of bar. This means that psi and bar often have to be converted into each other in everyday life. For an accurate calculation, the converter should definitely be used. However, for a rough calculation, the rounded conversion value of 14.5038 can also be used. The value in bar multiplied by 14.5038 gives the value in psi. Dividing the value in psi by 14.5038 gives the value in bar.

• Psi = bar * 14.5038
• Bar = psi ÷ 14.5038

Converting bar and pascal

Converting between bar [bar] and pascal [Pa] is very simple. A conversion value of 100,000 is used for the calculation. The value in bar [bar] multiplied by 100,000 gives the value in pascal [Pa]. Dividing the value in pascal [Pa] by 100,000 gives the value in bar [bar].

• Pascal [Pa] = bar * 100,000
• Bar = pascal [Pa] ÷ 100,000

Convert hectopascals and bar

On a barometer, air pressure is often given in hectopascals [hPa]. For meteorologists and other scientists, hectopascals [hPa] are therefore an important unit of measurement for air pressure, which means that conversion is often necessary. The two pressure units can be converted using a conversion factor of 1,000. The value in bar multiplied by 1,000 gives the value in hectopascals [hPa]. Dividing the value in hectopascals [hPa] by 1,000 gives the value in bar.

• Hectopascals [hPa] = bar * 1,000
• Bar = hectopascals [hPa] ÷ 1,000
