HI quick question on this topic please answer!

at sea level 14.7 psia is the same as 0 psig. is this true or false?

( i was confused because psia absolute 0 is at 0 and psig absolute zero reads 14.7 and i thought in order for this to be true if pisa is 14.7 shouldnt psig read 29.4 for it to be true? ) or am i wrong? please let me know thanks!

Please do not dig up topics this old. In this case, yes, 14.7 psia is 0 psig. That's only true if the gauge use to measure psig is calibrated at sea level on earth.

Spitfire, Hi .. Nice to see a fellow south african on here. here is what you do.
go to google and just type things like "1 bar in psi" it will show you the conversion...

So in answer to your last question .. go to google type "1 inch in cm" ... it's like magic i tell ya..
