Yes, curious myself!
But I am about to spend some support points to find out.

Unfortunately, these fields are not used in X-Cart, they remained from previous versions
of X-Cart.

They are not international. The values of these fields are stored in the 'xcart_products'
table in the 'dim_x', 'dim_y', 'dim_z' fields accordingly.

To display these fields, for example at the product details page, you can edit
'skin1/customer/main/product.tpl' (customers zone) and 'skin1/main/product.tpl'
(admins/providers zone) templates and use the following code there:
{$product.dim_x}
