CHAMBER GAS ADDITION CALCULATOR
Professional gas mixing calculations for diving chamber operations
Chamber Gas Mixing Formula
Calculate the depth equivalent of rich gas mixture needed to achieve target oxygen partial pressure:
✓ Depth of Rich Mix = (PO₂ Added - (Bottom Depth × Weak Mix %)) ÷ (Rich Mix % - Weak Mix %)
✓ All calculations account for proper unit conversions
✓ Results show step-by-step calculations for verification
Gas Mixing Calculators
Calculate rich gas depth for both metric and imperial diving operations
Metric Calculator (MSW/mbar)
Depth = (PO₂ Added - (Bottom Depth × Weak %)) ÷ (Rich % - Weak %)
Where PO₂ Added = Target PO₂ - Current PO₂
Where PO₂ Added = Target PO₂ - Current PO₂
Units: Depth in meters, PO₂ in millibars, percentages as decimals
Enter values and click calculate
Imperial Calculator (FSW/ATM)
Depth = (PO₂ Added - (Bottom Depth ÷ 33 × Weak %)) ÷ (Rich % - Weak %)
Result converted from ATM back to FSW × 33
Result converted from ATM back to FSW × 33
Units: Depth in feet sea water, PO₂ in atmospheres, percentages as decimals
