Problem With Price

Hello I have problem With my Shop.
When I set the price I see CAD, but the price per kilo of my products is because it is pastry that can confuse customers, how can I fix this? If I do I enter the field of weight it does not count the shipping charges ... Can you help me I am attaching to post some screenshots to better explain

Hi,

Cad. means each. I suppose. So if you want to change it to something else, you can override it as explained there:

The override should look like this:
PER_UNIT=" Kg."
