Ideal Gas Law Calculator
Solve PV = nRT for pressure, volume, amount of gas or temperature.
ToolPV
The ideal gas law PV = nRT is a model connecting pressure, volume, amount of gas and absolute temperature. This calculator converts the selected units to SI internally, solves for the chosen unknown, then converts the result back to the requested unit.
Real gases depart from ideal behaviour, especially at high pressure and low temperature or near condensation. Use the result as an ideal-gas estimate unless the conditions and substance justify a more detailed equation of state.
