I have a Clock an OEM #7132. Black with see through body. It has a temp area, but mine is stuck in Celsius and i want Fahrenheit

Just go to this webpage, it is explained in detail: with conversion table and formulas

Fahrenheit to celsius conversion

Convert Celsius to Fahrenheit and Fahrenheit to Celsius

Temp in F= (9/5) Temp in Celsius +32
F=(9/5) * C + 32
F(180)=(9/5)*180+32=356 F

switch in the back changes the setting

Press the Temp UP and DOWN buttons at the same time and hold for about 3 seconds to toggle between Celsius and Fahrenheit measurements.

with the switch in the 'lock' position, hit the C/F button (also labeled as the 'min' & 'date' button)

When the clock is in time mode the temperature is in the lower right hand corner. In this mode pressing the down arrow button will cycle from celsius to fahrenheit to seconds and then back to celsius.

Convert Fahrenheit to Celsius
Tc = (5/9)*(Tf-32)

Convert Celsius to Fahrenheit
Tf = (9/5)*Tc+32
where Tc is Temp in Celsius and Tf is temp in fahrenheit

It means to remove the little blue (mine are blue) squares on the two prong things( they have numbers next to them). With the blue things on the two prong numbered things on top of the unit it turns on the function of Celsius, 24 hr clock and other things. I had this same problem but I took the blue things off and reset my unit and it went to 12 hr clock and Fahrenheit. For me the Fahrenheit was the two prong thing labeled with the number 3 next to it. That's what the instructions mean by separating the control unit (blue thing is the control unit) from the wall mounted terminal (2 prong gold things with numbers.)

You can get the manual on link below.

You can switch the temperature mode between Fahrenheit to Celsius as follows:
While depressing the AUTO button, depress the OFF button for 3 seconds or more. The display will change from Fahrenheit to Celsius, or from Celsius to Fahrenheit."
