Hi,
Is there any formula for converting a given resistance of the (Siemens) NTC K164/1K5 into temperature in Celsius? I'm not familiar with components, but I need to use it in software.
You don't give enough information. How precise does your conversion need to be? A simple linear approximation works just fine for some ranges and for some applications. A second order curve handles many others.
For a more precise curve fit, search for the Steinhart-Hart thermistor equation.
Thank you for this info. Could you tell me what those a, b and c stand for?
Thank you for helping.

Ok, found it.. .
