Scuba Tank Capacity
Anthony Dupre
Scuba Tank Capacity is a precision gas calculator for scuba divers who want accurate gas content calculations—not just ideal gas estimates. Why Z-Factor Matters At high pressures (200+ bar), gases don't behave ideally. The Z-factor compressibility correction accounts for real gas behavior, giving you the actual usable gas in your tank—typically 5-10% less than ideal calculations suggest. Features: • Calculate actual gas content with Z-factor correction • Compare multiple tanks side-by-side • Support for Air, Nitrox, Trimix, and Heliox • Normoxic and hypoxic mix support for technical diving • Twin tank configurations with automatic volume doubling • Pre-configured tanks: Steel 6.8-18L (200/300 bar), AL63, AL80, AL100, HP80, HP100 • Pre-configured twin sets: Steel 6.8L, 7.5L, 10L, 12L, AL80, HP100 • Add unlimited custom tank and gas profiles • Temperature compensation (0-40°C) • Works offline—no internet required Built for Divers Whether you're planning a recreational dive or comparing tank options for technical diving, Scuba Tank Capacity gives you the numbers you need. See exactly how much gas each tank holds at your fill pressure and temperature. Perfect for: • Recreational divers planning gas consumption • Technical divers comparing tank and gas configurations • Dive shops and fill stations • Anyone buying or renting tanks No ads. No subscriptions. Just accurate calculations. Disclaimer This app is provided as a planning tool only. Always verify calculations independently and follow proper dive planning procedures.
