Dive Calculators

Calculate. Learn. Understand.

Diving is full of numbers: pressure, gas volume, SAC and RMV, depth, reserve, PPO₂, MOD, END and no-decompression limits. These tools are designed to make the mathematics easier to use and easier to understand.

Choose the Gas Management Calculator for a more structured dive-gas plan, enter the Calculator Fun Playground to experiment with smaller calculations, or use Calculate Units for quick metric ↔ imperial scuba conversions.

Educational tools: use the calculators to explore and understand dive mathematics. They do not replace formal training, verified dive planning procedures, appropriate tables/software, or a correctly configured dive computer.

Choose Your Calculator

Three quick paths: structured gas-management planning, a learning/calculation playground, and instant metric ↔ imperial scuba unit conversion.

Planning Tool

Gas Management Calculator

Build a practical open-circuit gas plan with cylinder size, start pressure, reserve, RMV, depth, descent/ascent rates, travel segments and user-defined stops.

  • Descent, bottom, ascent and travel gas
  • Safety/decompression stops
  • Backgas and optional stage cylinders
  • Automatic stage gas requirement
  • Depth/time profile and gas breakdown
Learning Playground

Calculator Fun Playground

Quick calculators for divers who want a useful answer without wrestling with the mathematics — and for anyone who wants to learn what changes when one number moves.

  • Weight / ballast estimate
  • Real SAC / RMV from a dive
  • Tank gas and time-at-depth
  • NDL, MOD, PPO₂, Best Mix and EAD
  • Trimix partial pressures, END and gas density
Quick Conversion Tool

Calculate Units

Fast metric ↔ imperial conversions for the units divers use most often, with instant updates in both directions.

  • Metres ↔ feet
  • Bar ↔ psi
  • Litres ↔ cubic feet
  • L/min ↔ ft³/min
  • kg ↔ lb, °C ↔ °F, m/min ↔ ft/min
Step-by-Step Guide

Calculator Tutorial Video

A walkthrough video will explain the calculators from top to bottom: what to enter, what each result means, and how to use the playground as a learning tool. The link position is prepared here and can be connected to the final YouTube upload later.

Important Safety Notice

Educational and Calculation Support Only

These calculators are designed to explain relationships and support dive-math learning. They are not a substitute for formal scuba or technical-diving training, qualified instruction, recognized procedures, validated planning software/tables, manufacturer guidance, or an appropriate dive computer.

Real dives must be planned and conducted within your training, experience, equipment limits and appropriate operational procedures. Always verify calculations independently when they are used for an actual dive.
