What does PSIG stand for in diving terms?

PSIG stands for Pounds Per Square Inch Gauge. This term is used in various fields, including diving, to indicate the pressure measurement of a gas or liquid in relation to atmospheric pressure. When using gauges that measure pressure, PSIG indicates the pressure above atmospheric pressure, which is critical in diving operations to ensure that divers are aware of the pressure within their equipment and environments.

In diving, understanding pressure measurements is vital for safety, as it directly impacts dive planning and execution. Pressure affects buoyancy and requires careful consideration of factors like descent and ascent rates, as well as equipment operation. The correct interpretation of PSIG helps divers and dive supervisors monitor conditions accurately, ensuring safety and effective dive management.
