CHAMBER PRESSURISATION CALCULATOR
Calculate gas volumes required for diving chamber pressurisation operations
Chamber Pressurisation Physics
Calculate the free gas volume required to pressurise a diving chamber to a specified depth equivalent:
✓ Gas Volume = Chamber Volume × Pressure Increase
✓ Pressure Increase = Depth ÷ Conversion Factor (10 for MSW, 33 for FSW)
✓ Accounts for proper unit conversions and gas law physics
Pressurisation Gas Volume Calculators
Calculate required gas volumes for both metric and imperial chamber operations
Metric Calculator (MSW)
Free Gas Volume = (Chamber Volume × Depth Added) ÷ 10
Where 10 is the conversion factor (MSW to bar)
Where 10 is the conversion factor (MSW to bar)
Units: Chamber volume in cubic meters (m³), depth in meters sea water (MSW)

Imperial Calculator (FSW)
Free Gas Volume = (Chamber Volume × Depth Added) ÷ 33
Where 33 is the conversion factor (FSW to atm)
Where 33 is the conversion factor (FSW to atm)
Units: Chamber volume in cubic feet (ft³), depth in feet sea water (FSW)
