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.
Use this formula: psi x 0.07031 = kg/cm2
Multiply by 0.036 http://www.enercongroup.com/conversion_factors.htm One PSI is equal to 27.7 inches of water column
to convert yards into feet, multiply the yards by three. 300 x 3=900 300 yards=900 feet.
300 g = 300000 mg
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.
Psi’s-14.696
add atmosperic pressure to gage pressure to convert to psia one atm standard = 14.7 psi
(psi x 6.89476 = kPa). So, 70 psi x 6.89476 = 482.633 kPa
psi is equal to psig...if psi is in the pressure gauge or psig..on a gauge
psia to psig psig - 15 15 - 15= 0 psig
How to convert wog to psi? For example 1000 wog how much psi?
1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.
1 bar = 14.5 psig so 3.5 bar = 51 psig (what your significate figures)
55 psig +15=70
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.
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.
