I find when I am baking I am constantly converting recipes, and I always have to do all this math in my head. I finally came up with this baking conversion chart to help with the math and keep it simple. Print it out and keep it in your cookbooks or on your fridge!
This one is for teaspoons and tablespoons. My biggest pet peeve is when a recipe has 5 Tablespoons or 6 teaspoons. Just convert it already and then I don't have to count out all those little spoons.... sheeesh.
