How does one convert a temperture to frequency (CPS) is this possible TIA
Is this possible if so what is the formula it's all emf isn't?

Thermister/divider output to a vco( voltage controlled oscilator )
basically.

You could use a couple thermistors, AKA temperature variable resistors,

The Analog Devices AD537 voltage to frequency converter will do this
DIRECTLY.
It's got some sort of temperature sensor in it. You'll have to look
for the right case for your application.
You could also use a cricket, but they're not so stable.
