+Pos to weight by product
+==============
+
+Motivation
+============
+
+At the moment, when we create a new product and choose the unity of measure **kg**, 
+we have to tick the checkbox 'To Weigh With Scale' in the Point of Sale part.
+
+We want to speed the process of creating a new product, avoiding filling manually this parameter.
+
+Brief presentation
+============
+
+This module adds the field **'To weigh'** in UOM categories (set to **false** by default).

+   :alt: Categories of unities of measure
+   :width: 900
+
+
+**→** This field affects every unities contained in this category.

+   :width: 900
+
+**→** **AND** it is linked with the parameter **to_weight** in product.template used for example in the Point of Sale app.
