The reason you're having issues converting superheat in Kelvin to Fahrenheit is that it's not Fahrenheit you're converting to. Superheat, etc, use an absolute scale, Rankine (Fahrenheit) and Kelvin (Celcius). Chuck "10 degrees Kelvin in Rankine" into Google and that'll give you what you want. You can only really convert between Rankine and Kelvin, and Fahrenheit and Celcius, not between all four.

Listening to your podcast on EMS and wondering which connectors you were mentioning that were Ferrules which you said you used for the grounds on MicroThermo boards.

I'm sure this is a great review for many people who have already been through this however for newer people I can't really say how good it is because the audio quality is Probably 78 to 80% Not necessarily dropping out a full 20% of audio but definitely Losing critical terms here and there makes it very very hard for somebody new to to refrigeration
