Know Before You GoCalculate Depth, Pressure, and Air Usage
This dive calculation tool helps recreational divers plan their dives more safely and accurately. Whether you’re preparing for a shallow reef dive or exploring a deeper spot within recreational limits, understanding the connection between depth, pressure, air consumption, and dive time is essential.
Use the tool below to estimate key dive parameters quickly.
The calculator provides useful results such as ambient pressure, oxygen and nitrogen partial pressures, and tank air volume. It also shows your air consumption at depth and the total volume of air you will inhale during your dive. You can calculate tank pressure based on temperature and see the maximum operating depths for oxygen and nitrogen exposure.
These calculations help you better understand your limits and plan your dive more effectively.
This dive calculation tool improves safety and awareness. It supports better air management, lowers stress, and helps divers make informed decisions. Although it’s not a replacement for dive computers or certified training, it serves as a helpful resource during dive planning.
Whether you’re a beginner learning to plan your first dives or an experienced diver refining your skills, this calculator connects theory with real-world diving. It’s especially useful for visualizing how different factors – like tank size, depth, and breathing rate – impact your overall dive plan.
Note: This calculator is for educational and planning use only. Always dive within your training limits. Use a certified dive computer and follow your dive agency’s guidelines for safety stops and depth limits.
