This is the official Social Diving scuba diving air consumption calculator. It’s free to use and I hope it will help you in planning your dives.
Scuba diving air consumption calculator
All you need to do is enter your desired diving depth, info about your scuba tank, and your respiratory minute volume (RMV). If you don’t know your RMV, use the RMV calculator below to find out.
Respiratory Minute Volume Calculator & Surface Average Consumption
If you don’t know your RMV (respiratory minute volume), enter the numbers from a previous dive and find out.
You can then use these values to enter your RMV above for a calculation of your expected air consumption.
The average RMV is somewhere between 12-25 L/min.
