PSIG
PSIG stands for pounds per square inch gauge and is a unit of pressure measurement in the maritime industry. It is the pressure measured relative to the local atmospheric pressure. PSIG is commonly used to measure the pressure of gases in tanks, pipelines, and other systems on board ships. It is important to note that PSIG does not take into account the atmospheric pressure, which can vary depending on the location and weather conditions. Therefore, it is necessary to convert PSIG to absolute pressure (PSIA) when comparing it to other pressure measurements.
