Hello,

Is there a formula to convert a certain radio frequency to temperature? Thanks.

What exactly do you mean?
If you mean the temperature of a black that emits a frequency in the radio then use wein's law.

for example, the FM station abc operates at 86.1mhz, what's the temperature is the radio wave emitting?

i think i have found the formula though.

do i use the frequency form formula?

fmax = (ak/h)(T)

The spectrum of a FM broadcast is not very similar to the spectrum of blackbody radiation at any temperature. I don't think the conversion makes sense.
