This is my friendly little scale, the Ultraship 55. It weighs in grams, and in 10ths of an ounce. You can tare it to weigh things in containers. I use it to weigh fleeces, bags of dyed locks, roving, skeins of yarn - you name it. Its the BEST Christmas present I ever got.
The one thing you really have to watch with these digital scales is to not put something heavier than they can weigh on them. It can ruin them! So I am cautious with my little friend. :^)
