    The formula is:
    °C = (°F − 32) × 5⁄9
    = (72 − 32) × 5⁄9
    = 40 × 5⁄9
    ~ 22°C

      But Michael still misrepresented that data by saying that the temperature was cut in half. Half of 100°C is around -87°C. Hint: absolute zero is at -273°C.

        In testing a Pi 3 today it does seem temperature sensitive. When I build the kernel (4.1.20) using all 4 processors (-j4) it will quickly heat up and freeze (pun intended). When using just a single CPU the temperature is as follows.

        temp=68.8'C
        frequency(45)=1000000000
        frequency(1)=500000000


        With 4 cpus it quickly goes north of 80 and stops. I need to try the same uSD in a Pi 2 but that has always built with a -j4 compile.
