SUMMARY
The universal gas constant, denoted as "R," varies based on the units used for measurement. It is defined as 0.0821 L·atm/(K·mol) when using liters and atmospheres, and as 8.314 J/(K·mol) when expressed in joules. The conversion between these values involves changing liters to cubic meters and atmospheres to pascals, illustrating that the value of R is contingent upon the chosen unit system. This principle is similar to converting speed measurements between miles per hour and kilometers per hour.
