I would add it as a custom model method - see:
https://docs.djangoproject.com/es/1.9/topics/db/models/#model-methods
So, for example:
class Temperature(models.Model):
user = models.ForeignKey(User, unique=False)
celcius = models.FloatField(null=True, blank=True)
def _get_fahrenheit(self):
"Returns the temperature in Fahrenheit."
return '%s' % (self.celcius * 1.8 + 32.0)
fahrenheit = property(_get_fahrenheit)
