The highest recorded temperature on Krypton was 142 degrees F. The lowest recorded tempera-
ture was −93 degrees F.
Express the low temperature extreme in degrees Celsius.
Answer in units of degrees C.
As the convertion formula from Farenheit o Celcius is C = (F - 32)*5/9, the lowest temperature on Krypton would be C = (-93 - 32)*5/9 ≈ -69.44 C
