Hi S.. I think it depends on the soup. For instance, if it is canned soup, look on the can. How many servings does it say is in a can? 2? Well devide the number of ounces the can contains and there is one serving, or bowl. I looked online for this as well and I did find a recipe for soup and it was worth 2 WW points and it was a cup and a third or soup. Sorry I'm not much help. Good luck on your new diet!
