Pascal Conversion: From Pascals to Bar, psi, atm, and Torr
The pascal (Pa) is the SI pressure unit, defined as one newton per square meter. In many practical fields—from engineering to weather forecasting—values are often expressed in other units such as bar, psi (pounds per square inch), standard atmospheres (atm), and torr. This Pascal Calculator serves as an efficient Pressure Converter: enter a value in pascals and instantly see its equivalents in all these major units, whether you need a conversion from pascals to psi, Pa to bar, or any other combination.
How to Use the Converter
Using the tool is straightforward. Type your pressure in pascals into the input field (for example, 100,000 Pa). The calculator immediately returns the converted values:
- Bar: 1 bar
- Atmosphere (atm): 0.986923 atm
- psi: 14.50377 psi
- Torr: 750.062 Torr
A drop‑down menu next to each result allows you to switch between different units or display additional equivalents such as kilopascals (kPa) or megapascals (MPa).
Conversion Formulas
Understanding the fixed relationships between these units enables manual calculation when needed. The following formulas use the defined conversion factors.
Pascal to Bar
One bar is defined as exactly 100,000 Pa. Therefore:
To convert bar back to pascals, multiply the bar value by 100,000.
Pascal to Atmosphere
A standard atmosphere is defined as 101,325 Pa:
Multiply the atm value by 101,325 to obtain pascals.
Pascal to psi
The pound‑per‑square‑inch (psi) is an imperial pressure unit. One psi equals 6,894.76 Pa:
To convert psi to pascals, multiply the psi figure by 6,894.76.
Pascal to Torr
The torr is defined as 1/760 of an atmosphere, which gives a conversion factor of 133.3224 Pa per torr:
Multiplying the torr value by 133.3224 returns the pressure in pascals.
Because the converter also supports related SI units (kPa, MPa) through the same underlying factors, it can handle virtually any common pressure conversion scenario.
FAQ
1. How do I manually convert pascals to psi?
Divide the pascal value by 6,894.76. For example, 100,000 Pa ÷ 6,894.76 = 14.50377 psi.
2. What is the exact factor to convert Pa to bar?
1 bar is exactly 100,000 Pa, so divide pascals by 100,000. To do the reverse, multiply the bar value by 100,000.
3. Does this pressure converter also handle kilopascals (kPa)?
Yes, because kPa is simply 1,000 Pa, the same conversion logic applies. You can view kPa equivalents through the unit drop‑down menus.
4. How can I convert atm to Pa using the provided formulas?
Multiply the atmosphere value by 101,325 to obtain pascals. Conversely, divide pascals by 101,325 to get atm.
