Question 1

What is a kilobar?

Accepted Answer

1 kbar = 1000 bar = 100 MPa = 14,504 PSI. Used in geology for Earth interior pressures.

Question 2

What pressures are measured in kilobars?

Accepted Answer

Earth's mantle: 1-140 kbar. Diamond formation: >40 kbar. Outer core: 1,400+ kbar.

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.
