I have one data file that Catherine passed on to me as the "official"
min/max file. It has some extra calculation in it that I stripped away
for the upload process, but no, nothing was a F to C conversion so I do
not have the F values in a table. I have found some F readings in the
hard copies from the early 80's so they exist, but I would have to enter
them again.

There were no decimal values giving in the F data that I scanned. It
just said "60"or "58". I don't know what kind of thermometer they were
working with back then.

I will, but I'll also print them out for Jeanne. She is more
knowledgeable than me on the weather docs.
