DALTON'S LAW CALCULATOR
Calculate partial pressures and gas percentages for diving applications
Find Partial Pressure
Partial Pressure = (Absolute Pressure × Percentage) ÷ 100
Enter values above
Find Percentage of Gas
Percentage = (Partial Pressure × 100) ÷ Absolute Pressure
Enter values above
Find Absolute Pressure
Absolute Pressure = (Partial Pressure × 100) ÷ Percentage
Enter values above
Depth & Pressure Conversions
Depth in feet or meters must be converted to pressure absolute
Bar to Meters
Depth(m) = (Bar × 10) - 10
Enter bar value
ATM to Feet
Depth(ft) = (ATM × 33) - 33
Enter ATM value
Meters to Bar
Bar = (Depth + 10) ÷ 10
Enter meters value
Feet to ATM
ATM = (Depth + 33) ÷ 33
Enter feet value
About Dalton's Law
Dalton's Law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. This calculator helps you determine partial pressures, gas percentages, and absolute pressures for diving and gas mixture applications.
