Question 1

What is a microbar?

Accepted Answer

1 μbar = 0.1 Pa = 10⁻⁶ bar. Used in acoustics for sound pressure. 20 μPa is threshold of hearing.

Question 2

Where are microbars used?

Accepted Answer

Sound pressure levels, vacuum systems, atmospheric research. 1 μbar = 0.1 Pa (very small pressure).

Question 3

What pressure units do different industries use?

Accepted Answer

PSI in US/UK automotive and HVAC. Bar/kPa in European engineering. mmHg/torr in medicine. Atmospheres in diving and altitude.

Question 4

Is gauge pressure different from absolute pressure?

Accepted Answer

Yes! Gauge pressure reads 0 at atmospheric pressure. Absolute pressure adds atmospheric (~14.7 psi). Vacuum gauge shows negative gauge pressure.
