Changing the temperature scale
Your Braun ThermoScan is shipped with the Celsius
(°C) temperature scale activated. If you wish to
switch to Fahrenheit (°F) and/or back from Fahrenheit
to Celsius, proceed as follows:
(1) Make sure the thermometer is turned off.
(2) Press and hold down the «start» button (IRT 4020)
or the «I/O» button (IRT 4520). After about 3
seconds the display will show this sequence:
«°C» / «SET» / «°F» / «SET» ...
(3) Release the «start» button / «I/O» button when the
desired temperature scale is shown. There will be
a short beep to confirm the new setting, then the
thermometer is turned off automatically.
Hope this works - says it's for models IRT 4520 and IRT 4020 (Type 6022, 6023)

The forumla for F -> C is, (F-32)*5/9 So C->F is, (C*9/5)+32 C=450 F=(450*9/5)+32 = 842 F
Use this formula to convert degrees Fahrenheit (F) to degrees Celsius (C): [°C] = ([°F] − 32) × 5⁄9
A temperature change by one degree on Celsius scale equals temperature change of 1.8 degree on Fahrenheit scale or F (Fahrenheit) = 1.8 C (Celsius) + 32
No. The relationship between Celsius and Fahrenheit temperatures: C = 5/9*(F-32) is linear. The rate of change is 5/9 F degrees per C degrees but the relationship is not proportional. 0 C is not 0 F.
0 C = freezing point of water = 32 F 100 C = boiling point of water = 212 F 100 - 0 C = 212 - 32 F, so a change of 100 degrees C = a change of 180 degrees F. Reducing this fraction, 5 C = 9 F 24.4 / 5 * 9 = 43.92 So 24.4 degrees above freezing in Celsius is 43.92 degrees above freezing in Fahrenheit. 32 + 43.92 = 75.93 F
