Maybe and maybe not. PSIA makes it explicit that the measurement given is an "absolute" value; that is, its zero point is a complete vacuum. PSI may be absolute, or it may be given relative to ambient atmospheric pressure.
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.
1000 pounds per square inch (ksi) = 6894.76 kPa, so 1 ton (2000 pounds) per square inch = 13789.52 kPa,and 20 tons per square inch = 275790.4 kPa = 275.7904 MPa[megaPascal].I used ConvertWorld to help with the conversions. See related link.20 tons per square inch = 275.790 megapascals20 tons/in2 = 40000 pounds/in2 (psi)Multiply psi by 0.006894759087 to convert from psi to MPa40000 psi * 0.006894759087 MPa/psi = 275.790 (Googled the conversion rate)
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
add atmosperic pressure to gage pressure to convert to psia one atm standard = 14.7 psi
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 x 6.89476 = kPa). So, 70 psi x 6.89476 = 482.633 kPa
14.7 psia represents standard atmospheric pressure, or 1 atm. PSIA is just psi with atmospheric pressure taken into account also.
PSIA is Atmospheric pressure determined by what sea level you're at it will differ its weird how it works 30 PSIA is like 15 PSI, that's not exact so don't go by cutting the numbers in half I'll get back to you on the specifics PSI is read just like a tire
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
Maybe and maybe not. PSIA makes it explicit that the measurement given is an "absolute" value; that is, its zero point is a complete vacuum. PSI may be absolute, or it may be given relative to ambient atmospheric pressure.
psia to psig psig - 15 15 - 15= 0 psig
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
30 PSIG is about equal to 45 PSIA. Saturation temperature from the steam tables at 45 PSIA is about 274°F. So the steam would be 274°F, or hotter if superheated.
Multiply psi x 0.07 to get atmospheres.
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
