+
+This module allows to choose an Unit Of Measure (UoM) for products
+weight and volume. It can be set product per product for users in
+group_uom.
+
+Without this module, you only have the choice between Kg or Lb(s) and m³
+for all the products.
+
+For some business cases, you need to express in more precise UoM than
+default ones like Liters instead of M³.
+
+Even if you choose another UoM for the weight or volume, the system will
+still store the value for these fields in the Odoo default UoM (Kg or
+Lb(s) and m³). This ensures that the arithmetic operations on these
+fields are correct and consistent with the rest of the addons.
+
+Once this addon is installed values stored into the initial Volume and
+Weight fields on the product and product template models are no more
+rounded to the decimal precision defined for these fields. This could
+lead to some side effects into reportss where these fields are used. You
+can replace the fields by the new ones provided by this addon to avoid
+this problem (product_volume and product_weight). In any cases, since
+you use different UoM by product, you should most probably modify your
+reportss to display the right UoM.

+
+Installation
+============
+
+Be aware, that this module only change the UoM but not the value.
+
+It's the same behavior as base Odoo when you change from Metric System
+to Imperial System.
+
+Configuration
+=============
+
+To change the default UoM
+
+1. Go "General Settings", then in "Products"
+2. you have to select a default unit of measure for weights and volumes.
+
+To change on a specific product
+
+1. Go the product form you can change the UoM directly.
+
+Usage
+=====
+
+Once installed and the 'Sell and purchase products in different units of
+measure' option is enabled, the 'Unit of Measure' field will become
+updatable on the 'Product' form for users with the permission 'Manage
+Multiple Units of Measure'.
+
+If the displayed value is 0.00 and a warning icon is displayed in front
+of the unit of measure, it means that the value is too small to be
+displayed in the current unit of measure. You should change the unit of
+measure to a larger one to see the value.
