O2 Percentage

Enter you depth and your Oxygen percentage. Click on the Calculate button. The program will calculate the equivalent air depth (EAD).
Use the EAD with the Recreational Diver Planner for dive planning.



To calculate the ending volume by hand use the following formula.

                    (1 - O2%) x (D + 33)       
            EAD =   ____________________ - 33
			     .79          
Where:
O2% is the oxygen percentage as a decimal number
D is your planned depth
