PSIA is Pounds per Square Inch Absolute, as opposed to PSIG which is PSI Gauge. PSIA is absolute pressure. For example, normal atmospheric pressure is about 14.7 PSIA, so a PSIA device connected to atmosphere would read 14.7. PSIG is relative pressure, so if system pressure is 15.7 PSIA, and atmospheric pressure is 14.7 PSIA, then PSIG would be 1.0

Is 0 mm hg equal to 0 psia and is 760 mm hg equal to 0psig?
760 mm hg = 0 psi gauge pressure
What is scfh of air?
scfh is a measure of fan capacity. standard cubic feet per hour measured at 60 degrees fahrenheit and 14.696 psia. (22C and 1 atmosphere)
What are the degrees latitude western?
Latitude is measured in degrees North and South from the North to South poles. Longitude is measured in degrees East and West starting with 0 at Greenwich, England.
How do you convert psig tp psia?
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.
Boiling point of water at 0 ATM?
At 0 ATM the boiling point is extremely low. For example at 0.0000034 ATM, the boiling point is -67.78 Celsius. In an ideal vacuum it would be even lower than this but I don't know if it would be 0K or not.

How do you convert 15 psia to psig?
psia to psig psig - 15 15 - 15= 0 psig
Is 0 mm hg equal to 0 psia and is 760 mm hg equal to 0psig?
760 mm hg = 0 psi gauge pressure
What does 14.7 psia represent?
14.7 psia represents standard atmospheric pressure, or 1 atm. PSIA is just psi with atmospheric pressure taken into account also.
100 psia to psig?
psia=psig+atmospheric pressure where, atmospheric pressure = 14.7psi therefore psig=psia-atmospheric pressure psig=100-14.7 psig=85.3psig
What is scfh of air?
scfh is a measure of fan capacity. standard cubic feet per hour measured at 60 degrees fahrenheit and 14.696 psia. (22C and 1 atmosphere)
How is psig changed to psia?
add atmosperic pressure to gage pressure to convert to psia one atm standard = 14.7 psi
How much psia does 10 in. Hg equal?
14.7psia = about 30inhg thus, let 14.7 be 15 for easier calculations if 15 psia = 30 inhg then 1 psia = 30/15 inhg therefore 1 psia = 2 inhg or 1 inhg = 0.5 psia so 10 inhg is about 5 psia hope this helps
What does 85 psia equals in psig?
70 psig
Does temperature affect tire pressure?
Yes, if the weather is hot - Air in the tire will expand slightly and will have an effect on the pressure as it wants to take up more room in size. If the weather is cold the air will contract and more air will be needed - the reason for the extra air is so that the tire doesn't go down. The Math: Pressure increases directly with Temperature. So there's an easy formula to use.Since 0 psig in a tire is really 14.7 psia and 0oC is really 273oK the temperature and pressure for the tires you fill is Start Pressure = (Pressure on the gauge + 14.7) psia, and Start Temperature = (Measured temp +273) . Temperature at the end = End Temperature = (Measured temp in C + 273), and pressure at the new temperature = End Pressure So: End Pressure = Start Pressure x End Temperature / Start Temperature Since End Pressure includes an extra 14.7 psia, subtract it out and that's the pressure on the gauge in psig.
How do you calibrate PSIA transmitter. use 14.7 and the range is ATM to 600 PSIA. What would the 4-20mA set points be.?
The difference between Absolute Presure and Gauge Pressure is 14.7psi. So zero gauge pressure (0psig) = 14.7 psia. 600 psig = 614.7 psia. Calibrate the tranmitter so 4mA is obtained at 14.7 psig and 20mA is obtained at 614.7psig. The span will be 600 psi in both cases.
What is PSIA?
psia IS the abbreviation. It stands for Pounds per Square Inch Absolute. When determining a pressure, you are typically measuring it with something that is subjected to atmospheric pressure (1atm~14psia) just like you and I. So say you inflate your tires to 35 psi and check it with a tire gauge. That reading is the GAUGE pressure, or psig. Typically, gauge pressures will not use the G at the end because people tend to be good enough at noticing that there's a difference between "psi" and "psia" and start to ask questions. The ABSOLUTE pressure is the gauge pressure plus the atmospheric pressure. Expressed in equation form, this looks like: psia = psig + atm -or- psig = psia - atm In the case of a vacuum, where there is less than atmospheric pressure, an absolute gauge will read positive values while a typical gauge will read negative values. The equation still holds true. Example: Absolute pressure = 4 psia 1 atm ~ 14 psia What is the gauge pressure? -10 psig 4 psia - 14 psia = -10 psig
Psia at sea level under standard condiions is?
14.696
