-14.7psig is the gauge pressure of an absolute vacuum.
In standard English: "What does psig mean?" The abbreviation stands for pounds per square inch gauge. PSI is a standard unit of pressure, which may be converted to/from Pascals. "Gauge" here means relative to surrounding atmospheric pressure. So a reading of 100 psig means a pressure of 100 psi *above* the atmospheric pressure, which is around around 14.7 psi at sea level, making 114.7 psi absolute pressure.
-5 something is wrong
The bottle should be exchanged for a fully charged cylindar.

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

55 psig +15=70
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)

The term would be psig not psi. Proper psig for any a/c unit auto or not is a 40 degree evaporator and you would convert 40 to psig runningng a pressure temperature chart with engine running at 1500 rpm. I its usin R-134A the psig that equals 40 degrees Fahrenheit is 34.9 psig =40 degrees Fahrenheit at 1500 rpm. In fact , 34.9 psig is the pressure for 40 degrees no matter how many rpm. Use 40 and be safe. Don't forget ,40 psig at idle will be much lower as rpm rises and evaporator could freeze up depending on humidity and ambient temp of truck inside.
