You are supposed to add that pressure to the atmospheric pressure.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
No. We need to know exactly what is meant by gage here. A piston tyre gauge measures pressures relative to atmospheric. A mercury barometer measures absolute pressure. A gauge that involves uncoiling of a coiled tube will measure absolute pressure (it will have to be calibrated). But a manometer which is open to the atmosphere on one arm will measure pressures relative to atmospheric pressure so the real pressure is the two added together.
These are not the same dimension. Pounds force is a unit of force. PSI means pounds per square inch, which is a unit of pressure (force per unit area). The word gage refers to the fact that a pressure gage measures the difference between the pressure on the inside of a container and the outside. Normal atmospheric pressure is about 14 psi, so if a container of compressed air (like the tires on your car) measures 10 psi with a gage, the absolute pressure inside the tire is 14 + 10 = 24 pounds per square inch. The total force acting on a square inch of the tire material is 24 pounds - 10 pounds from the inside, and 14 pounds from the outside. Note, I approximated the 14 psi atmospheric. The actual at sea level is "14.something", I just couldn't remember the exact amount

The smaller the gage the thicker the material; therefore, for the same material, 14 gage is stronger.
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure. Gage pressure only considers the pressure above atmospheric pressure, while absolute pressure includes atmospheric pressure as well. This affects pressure measurements in a system because gage pressure readings will fluctuate with changes in atmospheric pressure, while absolute pressure readings will remain constant regardless of atmospheric pressure changes.
Gauge pressure is calculated by subtracting the atmospheric pressure from the absolute pressure. It is important to note that gauge pressure readings are relative to atmospheric pressure. So, to find gauge pressure, you would subtract the atmospheric pressure from the total pressure reading obtained.
if the gauge pressure is 206 kPa, absolute pressure is 307 kPa
The gauge pressure would be 448.955kPa.
To calculate the gauge pressure of a system, subtract the atmospheric pressure from the absolute pressure of the system. Gauge pressure Absolute pressure - Atmospheric pressure.
The gauge pressure is the absolute pressure minus atmospheric pressure. If atmospheric pressure is considered to be 101 kPa, then the gauge pressure would be 219 kPa.
This is the following definition:Absolute pressure is the total pressure at a point in a fluid equaling the sum of the gage and the atmospheric pressures.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
abosulute pressure includes the atmospheric pressure while gage pressure gives the pressure above atmospheric pressure
Absolute pressure is the total pressure exerted by a fluid, including atmospheric pressure. Gauge pressure is the pressure measured relative to atmospheric pressure. They are related by the equation: Absolute pressure Gauge pressure Atmospheric pressure.
