Surface Air Consumption (SAC) & Respiratory Minute Volume (RMV) Calculator

This calculator determines a scuba diver's SAC and RMV rate based on the average depth, bottom time, gas used, and tank size. A diver's air consumption rate can be expressed in terms of either pressure (SAC = PSI/bar per minute) or volume (RMV = cubic feet/liters per minute).
