Frequently Asked Questions
How many PSI is 1 bar?
One bar is approximately 14.5038 PSI. Bar is commonly used in Europe while PSI is the standard unit in the United States.
What is the difference between atm and bar?
One standard atmosphere (atm) equals 1.01325 bar. They are very close in value, but atm is defined by the average sea-level atmospheric pressure while bar is a metric unit.
How do you convert mmHg to Pascal?
Multiply the mmHg value by 133.322 to get Pascals. For example, standard atmospheric pressure of 760 mmHg equals approximately 101,325 Pa.
What is a Torr vs mmHg?
Torr and mmHg are nearly identical units of pressure. One Torr is defined as exactly 1/760 of a standard atmosphere, which is approximately equal to 1 mmHg.
