I don't see that it matters. If you learn the normal operating temperatures of your K3 in C then knowing those numbers in F doesn't add any information. If the normal PA temp is 55C during a contest and you see it at 60C then you know you should back off a bit. 

The only time you need to convert is when you calibrate the temp sensors.
