okay, obviously i need to add units for the FAS ones.

                  cal
units = ------------------- x 10^(-6)
         (sec)(cm^2)(C/cm)


this is so simple.  it does not matter how many pounds of helium are in your 
tanks.  it is all relative.  you can look at this quantitatively or 
qualitatively.  you still get a higher thermal conductivity.  more helium in 
your mix at a higher thermal conductivity than air means a higher overall 
thermal conductivity for the mixture.  we don't need to solve this to 6 
significant digits to known the trend.  argon is denser than air and much 
denser than helium.

zambeck, stop chasing rabbits and call us back when everyone does not appear 
ten feet tall.
