Units for WooCommerce stores
If you sell to customers in different countries, product weight and dimensions affect shipping rates. WooCommerce stores them in the units set under WooCommerce → Settings → Products, so convert your supplier data to those units before importing products. Changing the setting later does not convert existing values.
