Bug!!! This has been discussed before. Here is the problem: 1_c is not one degree of c. It is instead 1 on the c scale which goes from -274 up. All of the additions on the 48 use absolute zero as a base. what is needed is the units "degrees of c" to go along with "c degrees" barring this, just remember to convert to K before you do any additions. This is annoying, but it is not a bug. Michael =============================================================================== Michael L.
