Easy Coconut Macaroons

"I can't tell from the recipe whether it calls for 16 ounces of coconut liquid measurement (as in 2 cups) or 16 ounces weight measurement (as in one pound.) When you purchase bags of coconut, it's by servings in tablespoons; when you purchase it from a natural food store, it's by weight. Why not just put the recipe one way or the other? Or, as I suggested, go to the metric system?"
