Hope it helps

Hi,

As you know, the price of a product is usually not directly linked to the UOM in the standard Odoo, but with some customization, this can be achieved.

you can inherit the uom category lines (uom.uom) and add a float field to store the price per UOM. 

now, Inherit the sale.order.line model and write an onchange for the UOM field to update the product unit price based on the price from the UOM chosen.

Thanks
