This is a screen shot from the professional units conversion program "Uconeer" from Katmar Software. It is designed specifically for engineers and scientists. Read full details of the Uconeer units conversion program.
The dedicated Gas Constant calculator in Uconeer calculates the value of "R" based on over 900 combinations of units, and will work with Energy or Pressure x Volume units. And if we have not included the Energy, Pressure or Volume units you need, you can easily add them yourself.
Tables of values of the Universal Gas Constant with the most frequently used combinations of units have been prepared from Uconeer for those who simply want to look up a particular value of "R" and don't want to download the complete program (but then you miss out on all the other great features of the Uconeer units conversion program).
