Nitrox planning
Use the calculator as a planning conversation starter
Find the rounded-down oxygen percentage for a target depth, then see MOD and equivalent-air-depth context.
Planning aid
Target depth and oxygen limit
Estimate the richest recreational nitrox percentage that stays within the selected ppO2 limit.
m
Rounded best mix
32% O2
MOD for that mix
33.8 m / 111 ft
Equivalent air depth
24.0 m
Planning boundary: Nitrox results require proper training, cylinder analysis, correct computer settings, operator confirmation, and respect for oxygen exposure limits. They are not clearance to make a dive.
