The custom field values will not be transferred while converting a lead to account, for these reasons:
- The custom fields have not been created for the Contacts, Accounts and Deals - You need to first create the fields in the Accounts, Contacts and Deals modules.
- The custom fields are not mapped with the fields in Contacts, Accounts and Deals - You need to map the custom fields in leads with those in the other modules.
To map fields

- Select the desired module and click Map Dependency Fields.
- In the Map Dependency Fields page for the selected module, click New.
