How this calculator works

P = nRT/V.

Formula

P=nRT/V

Pressure in atm from the ideal gas law using R=0.082057366080960 L·atm·mol⁻¹·K⁻¹.

Worked example

Verified example is a verified test case used by the calculation engine.

Assumptions and limitations

Volume must be positive.
Temperature is absolute temperature in kelvin.
The gas is modeled as ideal.
