Any websites/ charts that could help?

I bake a lot, and I'm always altering reciepes. Are there any sites that have like calorie charts for things by measurement? Like Sugar, then listed out by teaspoon, tablespoon, 1/4 cup ... I could make one, but if it's alreay been done ... ! And I was also wondering if anyone knows of anything you can plug a reciepe and servings into to get a stat breakdown for when I'm altering receipes. I'm doing it in a very complicated way right now! Thanks all
