Hi @Maharshi_Patel. In the Item master, you can set the Default UOM as Nos.

Then under Purchase and Sales details, you can mention the UOM as crtn.

In the UOM section, you can mention the conversion factor as shown below:

Finally, when the invoice is generated, the price will be shown for the default quantity UOM.

Hope this helps.
