Calculators and tools
Small, transparent calculators. Each shows its formula. None of them plans a dive or calculates decompression.
- Depth to pressure calculator
Convert water depth to gauge and absolute pressure in bar, atm and psi, for sea water or fresh water.
- Diving unit converter
Convert length (m, ft), pressure (bar, kPa, MPa, psi, atm) and volume (L, m³, ft³).
- Cylinder free-gas volume
Nominal free-gas volume of a cylinder or bank from its water capacity and fill pressure.
- Gas partial pressure at depth
Dalton's law: the partial pressure of one gas in a mix at a given depth.
- Certificate expiry planner
Work out a certificate's expiry date from its issue date and validity period, and how many days are left.
What you will not find here
Explanation Marine Deep's explanation, not a requirement.
We do not publish decompression, no-stop, gas-endurance or maximum-operating-depth calculators, and we will not generate them automatically. Those calculations belong to validated tables and procedures that your company and the applicable regulations specify. Why.
