The default temperature reading is in °C. If you enter “yes” for “Fahrenheit”, the temperatures will be
shown in °F. Temperatures displayed in Fahrenheit or Celsius can be converted using a relatively

C
and T
F
are the number of degrees Celsius and respectively
the number of degrees Fahrenheit:
Absolute Relative
°F = 32 + (°C * 9/5) °F = °C * 9/5
°C = (°F -32) * 5/9 °C = °F * 5/9
19.5°C = 32 + 19.5* 9/5 = 67.1°F 3.1°C = 3.1* 9/5 ≈ 5.6°F
