This calculator converts between the equilibrium constants Kp (expressed in terms of partial pressures) and Kc (expressed in terms of concentrations).
Start with your values, or try a preset.
Enter Kc (Equilibrium Constant in terms of concentration), Temperature, Change in number of moles of gas (Δn), and Ideal Gas Constant (R) in the units shown.
Read Kp (Equilibrium Constant in terms of partial pressure) in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
See the inputs and their calculated results.

Calculates the volume or number of moles of a gas at Standard Temperature and Pressure (STP). STP is defined as 0°C (273.15 K) and 1 atm pressure. This calculator uses the ideal gas law to perform these calculations.
Calculates the melting point of a substance based on the provided pressure. This calculator uses a simplified model and is most accurate for substances with well-defined melting points. Note: This calculator provides estimations and should not be used for critical applications.
Calculates the osmotic pressure of a solution using the van't Hoff equation. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
Calculates the Van't Hoff factor (i), which represents the number of particles a solute dissociates into in a solution. This factor is important in colligative properties calculations.
