drees,
The first time I logged internal temperature I was shocked at the large values until I realized it was in Kelvin. So, 2.947354E002 —-> 294.7354 degK – 273.15 conversion constant = 21.585 degC. Similar to the timestamp conversions, I usually make another column in Excel spreadsheet and let Excel do the conversion of all the temperature data (to degF since I am in the USA).
