How many carbohydrates equal one lb of fat?

There is no answer for that...

According to diet specialist Montignac, it works like this:

If you eat carbs you, in fact, tell your body: "Store all incoming fat"

So if you eat french fries, that is patato (carbs) baked in oil (fat)

Then you give your body the "store fat" command (carbs)

and at the same time, give fat to store. (oil)

Result: You become fatter.

If you just eat carbs... You wont get fat

If you just eat fat... You wont get fat

It is the combining of the two, carbs and fats, that triggers the fat storage process of your body. Making you fat.

So your question is unanswerable, It doesnt work like that.
