Automatic Volume Detection

The product's dimensions are read straight from its name — e.g. a product named Tile 600x200x225 is parsed as 600 mm x 200 mm x 225 mm, and the per-piece volume (in m³) is derived from that automatically. No separate dimension fields need to be maintained.

CBM → Pieces

Whenever the CBM quantity changes, the Pieces field recomputes automatically:

Pieces = ceil(Quantity / Volume per piece)   if Quantity > 5
Pieces = round(Quantity / Volume per piece, 2)   otherwise

Ceiling rounding is used for larger quantities so that a partial piece is never under-counted.

Pieces → CBM

Pieces can also be edited directly (in the UI). When a user changes the Pieces value by hand, the quantity is recalculated the other way:

Quantity = Pieces x Volume per piece

This bidirectional flow works without creating an update loop — the module uses a context flag / value comparison to detect whether the change was triggered by quantity or by pieces before recomputing.

Works Across Documents

The Pcs column is available on:

Requirements

• Odoo 19.0
• Standard Odoo apps: account, sale_management, stock (installed automatically as dependencies)

Steps

1. Copy the cbm_converter folder into your Odoo addons path.
2. Restart the Odoo server (or update the apps list).
3. In Odoo, go to Apps → search for CBM Converter → click Install.
4. Open any Sale Order, Invoice, Delivery, or Return Picking — the Pcs column appears next to the Quantity column (toggle via the optional columns menu if hidden).
