How it works
Fill in the 3 fields above and Dalton’s Law Calculator calculates the result instantly, recalculating as you change any value. It applies the formula P_total = P₁ + P₂ + P₃. The math runs locally in your browser — nothing is sent to a server.
Formula
P_total = P₁ + P₂ + P₃Examples
- Partial pressure 1 20 kPa, Partial pressure 2 30 kPa, Partial pressure 3 15 kPa → Total pressure: 65 kPa
