Question 1

How do I convert kPa to PSI?

Accepted Answer

Multiply by 0.145 or divide by 6.895. 200 kPa = 29 PSI. 100 kPa ≈ 14.5 PSI.

Question 2

What is 100 kPa in PSI?

Accepted Answer

100 kPa = 14.5 PSI ≈ 1 atm (actually 0.987 atm). This is approximately atmospheric 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.
