Cinnamon Stick vs. Ground Cinnamon

I was reading a recipe that called for a cinnamon stick. I was wondering how much a stick was compared to ground cinnamon. I found this link: Cinnamon Stick. For about one, 3 inch cinnamon stick, it takes about 1/2 teaspoon of ground cinnamon. This site also has some other substitutes for ground cinnamon.
