The formula is written as PV=nRT.

Seems like they had a logical progression going on in regards to labeling for the most part:

Pressure being a P,

Volume being a V, and

Temperature being a T.

But the Gas Constant being labeled R makes no real sense. Maybe it was a random letter chosen, but I suspect the real answer might prove interesting.


Quote from Wikipedia

Some have suggested that it might be appropriate to name the symbol R the Regnault constant in honour of the French chemist Henri Victor Regnault, whose accurate experimental data were used to calculate the early value of the constant; however, the exact reason for the original representation of the constant by the letter R is elusive.
