Sac Rate Calculator

The formula SACRate=ACD/DT/P​ represents the calculation for Specific Air Consumption Rate (SAC Rate) in diving. Each variable in the formula has a specific meaning:

• $SACRate$: Specific Air Consumption Rate, which measures the rate at which a diver consumes air during a dive. It is typically expressed in units like pounds per square inch per minute (psi/min).
• $ACD$: Air Consumed During Dive, representing the amount of air used by the diver throughout the dive. This is often measured in pounds per square inch (PSI).
• $DT$: Total Dive Time, denoting the duration of the dive, typically measured in minutes.
• $P$: Pressure at Depth, indicating the pressure experienced by the diver at the depth they are currently at. This is usually expressed in atmospheres (atm).

The SAC Rate is a critical metric for divers, as it provides insights into their air consumption efficiency under specific diving conditions. A lower SAC Rate signifies greater efficiency, indicating that the diver is using less air to cover the same amount of time and depth. This information is essential for divers to plan and manage their air supply during a dive, contributing to a safer and more enjoyable underwater experience. Keep in mind that individual factors, equipment, and diving conditions can influence the SAC Rate, so consistent monitoring and understanding of one’s SAC Rate is crucial for responsible diving practices.
