#### [v8] Is Odoo able to manage products that work with variable units of measure?

I am facing serious problems trying to implement Odoo to work with products that use two units of measure and the conversion between them is variable. This seems to be a very common scenario in many industries, that you buy and sell a product in "Pieces" but you manageyour stock and have the prices of the Kg.

Example: Food industry dedicated to buy and sell chickens and other poultries.

- We buy chickens by units (we make purchases orders saying "Send me 1000 chickens") but we negotiate the price with the supplier by Kg, say 1€/Kg.
- When we make a purchase order we do not know in advance how many Kgs correspond to 1000 chickens (well, we have an aproximate idea of how many Kg will weight a chicken, an average weight, say 2Kg/chicken, but not the exact weight that the delivered 1000 chickens will have on arrival).
- When we receive the chichens, we weight them and input in stock the exact Kgs they weight, let's say 1900 Kgs.

When we sell:

- Our customers, groceries stores and restaurants, ask us for chickens also in units ("hey, send me 20 chickens!"), so our salesmans fill the Sale Order with 20 chickens.
- The price we give to our customers is by Kg, say 3€/kg
- As with purchases, when the customer places the Sale Order we do not know exactly how much will weight the 20 chickens.
- When we prepair the delivery order is when we weight 20 chickens and input it in the order, say the 20 chickens = 38.750 Kgs
- If we invoice the delivery order, the line should show up 20 chichens and/or 38.750 Kgs

This operative seems pretty straightforward and should mean no problem, given Odoo is able to work with two units of measure, but I am unable to make it work correctly.

I configure the product as:

Product: Fresh chicken
UoM: Kg
List Price: 3€
UoP: Unit
Uos: Unit
UoS -> UoM Coeff: 0.5

In the Sale Order I can input 20 chicken and automatically 40 Kgs are calculated, no problem with that, is obviuosly an stimated average weight. Is when I go to the Delivery Order that I input the actual weight, 38.750 Kgs, and it is then when Odoo also converts that to 19.375 chickens!! If I make the invoice of the order, the invoice line will show:

Product              Quantity     UoM      Quantity    UoS    Unit Price      Subtotal
========        =======    ====    =======    ===    =======    ========
Frech chicken     38.750        Kgs        19.38      Units       3.00€        116.25€

When it should show

Product              Quantity     UoM      Quantity    UoS    Unit Price      Subtotal
========        =======    ====    =======    ===    =======    ========
Frech chicken     38.750        Kgs         20.00     Units       3.00€        116.25€

Am I doing something wrong, facing the problem the wrong way, or is it simply that Odoo can not work with products with variable units of measure?
