It means pounds per square inch gauge and Is used to measure pressure
0.5 psig = 420.62 inches of water column.

PSIG is psi Gauge, i.e. does not include air pressure. PSID is psi differential, checks for delta-P across things like filters, pumps, etc.
minimum pressure is 525 psig for R-410A
(psi x 6.89476 = kPa). So, 70 psi x 6.89476 = 482.633 kPa
psia to psig psig - 15 15 - 15= 0 psig
psia=psig+atmospheric pressure where, atmospheric pressure = 14.7psi therefore psig=psia-atmospheric pressure psig=100-14.7 psig=85.3psig
70 psig
psig
55 psig +15=70
Up to about 150 psig or so. Yes. Graphite is used for shaft seals on steam powered equipment.
0.5 psig = 420.62 inches of water column.

PSIG refers to pound/force per square inch gauge, while PSI measures the pressure relative to a vacuum. If you want to convert a figure from PSIG to PSI, you would need to add 14.7psi to your PSIG figure, which will give you your PSIA result.
1 bar = 14.5 psig so 3.5 bar = 51 psig (what your significate figures)
