Well, as far as temperature ranges go, the cooker temp can be as high as 500F. The meat temp as high as 230F.

The adjust value for the raw ADC value is actually 1.64 for the meat thermocouple I am using. That was the reason for the 'times 100'.

I suppose it could be done with longs since I am using an 18F2550?

Thanks again for the advice
