U rgent:"i want to know the work of this "conversion routine".

Question

Hi all,
In the domain of any field in the  database table there is one option called "conversion routine" just below to "output list".
i want to know the work of this "conversion routine".
can any one please tell me the practical use of this with  real time example.
good points will be rewarded for helpful answer.
thanks in advance
