Frequently Asked Questions

What is the standard atmospheric pressure?

Standard atmospheric pressure is defined as 101,325 Pascals, or 1 atm. This is equivalent to 760 mmHg, 14.696 psi, or 1.01325 bar.

Are mmHg and Torr the same?

Practically, yes. 1 Torr is defined as exactly 1/760 of an atmosphere, which makes it nearly equal to 1 mmHg. They are often used interchangeably in vacuum and medical measurements.

Why are there so many pressure units?

Pressure units evolved from different measurement systems (metric vs imperial), and different industries adopted specific units for convenience. For example, psi is common in the US, while Pascals and bars are widely used elsewhere.
