Thermistor Calculations

Context

Problem

The ADC for the temperature sensor takes in voltage from a thermistor. We need to convert this to the temperature. However, different thermistors affect the voltage calculation in different ways relative to the units that are used. For example, during 2022-23's development cycle, the thermistor's temperature coefficient was given in terms of millivolts/degree Celsius. Meanwhile, the 2023-24 thermistor used had its temperature coefficient given in ohms/degree Celsius.
