Fat Loss Questions: How many calories does it take to burn 1 lb of fat and 1 gram of fat

I have question.  How many calories do you need to burn one gram of fat?  I know there is 9 calories per on gram of fat, but how many calories would it take to burn one gram of fat? 9?

Thanks,

The Amount of Calories You need to Burn to Lose Fat

You must burn about 3500 kcal to burn 1 lb of fat. (1 pound = 453.59237 grams)

So it takes 7.7 cal to burn 1gram of fat.
