Question 1

How do I convert PSF to PSI?

Accepted Answer

Divide by 144. PSF = pounds per square foot. 1 PSI = 144 PSF. Used in structural engineering.

Question 2

What is typical floor loading in PSF?

Accepted Answer

Residential: 40 PSF. Office: 50 PSF. Library stacks: 150 PSF. Heavy industrial: 250+ PSF.

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.
