Diving involves careful planning and knowledge about its impact on your body. Use Wolfram|Alpha, which has PADI, NAUI and nitrox calculators, to create and review your diving profile.


Explore a diving profile, including pressure groups, time restrictions and stop requirements based on the duration, depth, surface interval and initial pressure group of your dive.

Do recreational dive calculations interactively:

Calculate the pressure group after a dive:

Include a pressure group and surface interval:

Nitrox Calculator

Calculate dive depth or oxygen partial pressure for a given nitrox composition.

Compute dive depths for nitrox mixtures:
