Frequently Asked Questions
How do I convert bar to PSI?
Multiply the bar value by 14.503773773, since one bar equals about 14.5 PSI. For example, 2 bar is about 29 PSI. The tool shows the exact figure.
How many pascals are in a kilopascal?
There are 1000 pascals in one kilopascal. To convert kPa to Pa multiply by 1000; to go the other way divide by 1000.
What is standard atmospheric pressure?
One standard atmosphere equals 101,325 pascals, which is about 1.013 bar or 14.7 PSI. You can confirm this by entering 1 with atmosphere selected.
What is mmHg used for?
Millimeters of mercury are commonly used for blood pressure and weather readings. One mmHg equals about 133.32 pascals.
Is my data sent anywhere?
No. The conversion runs entirely in your browser, so the values you enter never leave your computer and it works offline once loaded.
Can I compare several pressure units?
Yes. The table converts your value into every pressure unit at once, so you can read Pa, kPa, bar, PSI and atm together.
