Partial Pressure Calculator (Daltons Law)
Calculate individual gas partial pressures in a gas mixture from total pressure and mole fractions.
Input Parameters
Instant Real-time CalculationDaltons Law of Partial Pressures states that in a mixture of non-reacting gases, total pressure equals the sum of the partial pressures that each gas would exert alone.

- 3 Read the partial pressure of the component.
Partial Pressure Calculator (Daltons Law) — Frequently Asked Questions
Q1 Why is partial pressure critical in physiology and diving? ▾
Gas exchange in the lungs and tissues is driven strictly by partial pressure gradients (pO2 and pCO2), and high partial pressures of nitrogen at depth cause nitrogen narcosis.
