How many calories in one cup of wheat flour?

One cup of all-purpose wheat flour contains approximately 455 calories.

However, this can vary slightly depending on:

* The specific type of wheat flour: Whole wheat flour, for example, will have slightly more calories than white flour.

* The density of the flour: A tightly packed cup of flour will have slightly more calories than a loosely packed cup.

It's always best to check the nutrition label on the specific bag of flour you are using for the most accurate calorie count.
