Osmotic Pressure Calculator

Calculate osmotic pressure using Π = i × C × R × T. Find osmotic pressure (Π), concentration (C), temperature (T), or molar mass. Supports pressure units (Pa, kPa, atm, bar, psi, mmHg), concentration units (mol/m³, mol/L, mmol/L, μmol/L), temperature units (K, °C, °F), and van't Hoff factors for electrolytes (NaCl, CaCl₂, etc.). Perfect for chemistry and biology students.
