of chamber pressure. Before about the 1960's the only measurement system we had for chamber pressure was the copper crusher method. Up until that time, what we now call CUP was commonly known by two different names: CUP and PSI. The two were used practically interchangeably. Of course, this use of PSI was incorrect. It wasn't much of a
