as I remember it wwas a formula for using his data tables... but it was several month's ago, If I get a chance tonight (9:23P) I will go look at his website again and if not I already has a note for me to do it in the morning when I am 'fresher' and I should have the stuff posted or at least a link or URL directly to the data. Hope this helps and I still think that you might consider another measurement method as what you are describing would be a bear to replace and re-calibrate a thermistor or at least you might see just how well the cal holds for a 'different' thermistor, not one of the same batch. Again, just some random thoughts.
