OK either way. A meter^2 per second^2 is exactly the same as a
pascal per kg per meter cubed, or if you prefer a pascal meter cubed per kg.
But as with excess escape energy per kg, we would have smaller exponents
with the kinds of materials we care about if we expressed them as
km^2/sec^2, or perhaps Megapascal meter^3 per kg. Or kPa-m^3/gram,
whichever you prefer. Doug, I knew you'd come thru on this, you
never let us down when it comes to rockets. Why dont you come up
here and work for LMSC?
