gasConstant is the molar gas constant R, used in the ideal gas law and thermodynamics.
In PV = nRT, use absolute temperature in kelvin and compatible SI units. It equals avogadro times boltzmann. Do not apply the ideal-gas equation uncritically at extreme pressures or low temperatures.
Enter gasConstant on a calculator line to see its built-in value, or place the name inside a longer expression. Keep any displayed unit attached when converting or combining physical quantities, and check that every other value uses a compatible dimension.
The example above is editable, so you can replace surrounding values and test the constant in your own formula. Browse all constants to compare related values and notation.
