After the Cup x's PSI thread did not quite give me all the exact answers I wanted, I thought I'd post this link to something I found long time ago in a similar quest for conversion info. Check it out. If you enter a value in one box & hit "Calculate" it will fill in All the box's.

It will give you data for : Pressure - except the CUP x's PSI I wanted, Temp, Length, Weight & Volume.
