Hi-
Apply what the others told you:

=0.9998395+6.7982999*1E-5*b3-9.1060255*1E-6*b3^2+1.0052729*1E-7*B3^3-1.1267135*1E-9*B3^4+6.5917956*1E-12*B3^5

This seems to work in my Excel, although Excel converts it to this:
=0.9998395+6.7982999*0.00001*B3-9.1060255*0.000001*B3^2+1.0052729*0.0000001*B3^3-1.1267135*0.000000001*B3^4+6.5917956*0.000000000001*B3^5

This is called a polynumeral and is a standard way of approximating a 
formula, or rather making up a formula that will reproduce measured 
values.  In this case it converts temperature to the density of water 
(which is really close to 1).
