the gas constant occurs in the ideal gas law, as follows:









































where "p" is the absolute pressure (si unit pascals), "v" is the volume of gas (si unit cubic metres), "n" is the amount of gas (si unit moles), "m" is the mass (si unit kilograms) contained in "v", and "t" is the thermodynamic temperature (si unit kelvins). "r" is the molar-weight-specific gas constant, discussed below. the gas constant is expressed in the same physical units as molar entropy and molar heat capacity.

from the ideal gas law "pv" = "nrt" we get:

the stability of the ipk was crucial because the kilogram underpinned much of the si system of measurement as it was defined and structured until 2019. for instance, the newton is defined as the force necessary to accelerate one kilogram at one metre per second squared. if the mass of the ipk were to change slightly then the newton would also change proportionally. in turn, the pascal, the si unit of pressure, is defined in terms of the newton. this chain of dependency follows to many other si units of measure. for instance, the joule, the si unit of energy, is defined as that expended when a force of one newton acts through one metre. next to be affected is the si unit of power, the watt, which is one joule per second.
