FAQ
How many PSI are in a bar?
There are approximately 14.5038 PSI in one bar. Conversely, one PSI equals approximately 0.0689 bar. Bar is commonly used in Europe, while PSI is standard in the US.
What is standard atmospheric pressure?
Standard atmospheric pressure at sea level is defined as 101,325 pascals (Pa), which equals 1 atmosphere (atm), 1.01325 bar, 14.696 PSI, or 760 mmHg.
What is the difference between torr and mmHg?
Torr and mmHg are nearly identical units. One torr equals exactly 1/760 of an atmosphere, while 1 mmHg equals the pressure of 1mm of mercury at 0°C. The difference is less than 0.000015%.
