[diyana]

hi,
i have designed a adc..... i want to convert the output of ADC(digital o/p) to a Celsius value..is there any formula to convert that..... pls help to solve tis problem....

I think you are using a temperature sensor where it can senses the temperature of the room and generates an output voltage signal.
look into this link, you may get an idea how to calculate

...or are you using a thermistor/voltage divider? (Or even a thermocouple now I think about it?
If you can describe the relationship between sensor temperature and ADC input voltage, you're 80% of the way there!

What sensor are you using?
