# Configuration

The Product Module uses some settings from the `[product]` section of the configuration file.

## `price_decimal`

The `price_decimal` setting defines how many decimal places are used when storing Products’ <concept-product> unit prices.

Warning

Once the database has been created you cannot reduce this value, doing so will break your system’s data integrity. Also if you want to increase this value you must also manually change it in the database IR Configuration <trytond:model-ir.configuration>.

The default value is: `4`

## `uom_conversion_decimal`

The value from the `uom_conversion_decimal` setting defines the number of decimal places used when storing the conversion rates and factors between Units of Measure <model-product.uom>.

Warning

Once the database has been created you cannot reduce this value, doing so will break your system’s data integrity. Also if you want to increase this value you must also manually change it in the database IR Configuration <trytond:model-ir.configuration>.

The default value is: `12`
