I have had a rather bad run of luck with scales recently, having to return two faulty sets and not in the mood to purchase another just now whist awaiting refunds. One of my faulty sets was quite expensive so it has made me a bit wary.
Seeing as I only wish to use them for weighing pasta, is there any other way (bar using a cup) of doing so? Is there a way to determine calorie by strand or piece? 
Cups are useless as the shapes vary so much but not a lot of info online concerning cals per piece. One site suggested 3 cals per piece of rigatoni, but not sure.
I am hoping someone at some point measured the calorie per grams and took a photo, say 15 pieces of penne are 100 cals, etc.
Any ideas?
