@api.onchange('uom_id.id')
def onchange_unite(self):
    if self.uom_id.id == 'M3':
        self.quantity = self.quantity / 700

    elif self.uom_id.id == 't':
        self.quantity = self.quantity / 1000

    else :
        self.quantity = self.quantity / 1

Hi,

In your function it seems in the if condition your are checking the id of the chosen unit of measure,  the id will always a integer value, might be M3, t will be the names of the unit of measure. 


If they are the names of the Unit of measure,  instead of the self.uom_id.id in the conditions use self.uom_id.name . Also change this @api.onchange('uom_id.id') to  @api.onchange('uom_id')


Also by putting some print statements or logger messages inside the function, make sure that the function is getting executed during the onchange.


Thanks

is the above function is not working ? there might be some default function which work on this onchange, you can check the code by searching the onchange of this field and rewrite that function or super it. By putting a print statement in this function and see whether it is working or not
