Absolute pressure is the actual existing pressure, independent of the environment, while gauge pressure is the pressure relative to the exterior environment, which is usually the atmosphere (with a pressure of 1 atm).
Convert an absolute pressure of 7.25 × 105 N/m2 to gauge pressure, in pounds per square inch.
Pg= ?
The local atmospheric pressure is 757.8 mmHg. Express 1.254 atm absolute in terms of (a) dynes/cm2 absolute and (b) psi gauge.
