Okay, here is the whole formula, and I am going to put SMALL RAISED NUMBERS
INSIDE [].

T is temp centigrade

water density g/cm3 =
0.9998395 + 6.7982999 * 10[-5](T)
-9.1060255 * 10[-6](T[2]) + 1.0052729 * 10[-7](T[3])
-1.1267135 * 10[-9](T[4]) + 6.5917956 * 10[-12](T[5])

It is written on 3 lines as I have done. It looks like ranges of temp need
to be entered but no mention of that is made.

Thanks
