What this tool does
Convert bar to psi, kilopascals, atmospheres, pascals, megapascals, torr, mmHg, inHg and millibar. Type an amount in bars, choose the units, and the tool converts it to pounds-force per square inch (psi). It offers 10 pressure units and also shows the same amount in the others.
Inputs
- Value: A number.
- From: Choose one from 10 options, including Bar, Millibar, Pascal, Kilopascal, Megapascal, Standard atmosphere. Starts as Bar.
- To: Choose one of the same 10 units as "From". Starts as Pound-force per square inch (psi).
How to use
- Enter the amount you want to convert.
- Choose the unit to convert from and the unit to convert to.
- Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.
Worked examples
Conversions from bars to pounds-force per square inch (psi):
- 1 bar ≈ 14.503774 psi
- 5 bar ≈ 72.518869 psi
- 10 bar ≈ 145.037738 psi
- 50 bar ≈ 725.188689 psi
- 100 bar ≈ 1,450.377377 psi
Multiply the number of bars by about 14.503774 to get pounds-force per square inch (psi). The factor follows from exact definitions. It has more digits than fit here, so it is shown rounded.
Sources: Bar: SI Brochure, 9th edition (2019), Table 8 note. Pound-force per square inch (psi): exact by definition.
Limitations
- Converts pressure units only. It does not work out pressure from force and area, depth or altitude.
FAQs
- Q: How many pascals are in one bar?
- A: One bar is exactly 100,000 pascals, or 100 kilopascals.
- Q: How many psi is one bar?
- A: One bar is about 14.504 psi.
- Q: Can I convert to bar as well as from it?
- A: Yes. Choose bar as the To unit and any other pressure unit as the From unit.
- Q: Are torr and mmHg the same here?
- A: They differ by about one part in seven million, which is far below what any gauge shows. Both are listed so you can pick the one your instrument uses.
