Sea Level Pressure is defined as what psi?

Explanation:
Sea level pressure is the standard atmospheric pressure at the Earth’s surface and is used as the baseline in many hydraulic calculations. It is defined as 14.7 psi, which corresponds to about 1013.25 millibars or 29.92 inches of mercury. This means that gauge readings are typically relative to this ambient pressure, so at sea level a zero gauge reading plus the ambient pressure gives an absolute pressure of about 14.7 psi. The value 14.7 psi is the conventional reference for sea level pressure, making it the correct choice.
