I WAS going to make some sort of comment about how many sandwiches one could make using that much pastrami, but I won't. What I WILL say is that I did a bit of digging on the Cubic Foot and refreshed my memory that when it is used to measure gas there are addtional variables considered. Temperature of the gas (60 degrees F) and pressure (14.7 PSI). The almighty W points out that this makes a cubic foot a measure of quantity and not volume. I wasn't able to find out where they got the 14.7 PSI from.
