#Convert voltage to temperature formula code

Should I add something to the code below, enable some peripheral or my calculations are wrong? #define TEMP_SENSOR_AVG_SLOPE_MV_PER_CELSIUS 2.5f Each time, the value from ADC conversion is 296 which results in negative temperature. I'm trying to read internal temperature sensor.
